Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

Asynchronous conferencing or asynchronous computer-mediated communication (asynchronous CMC) is the formal term used in science, in particular in computer-mediated communication, collaboration and learning, to describe technologies where there is a delay in interaction between contributors.[1] It is used in contrast to synchronous conferencing, which refers to various "chat" systems in which users communicate simultaneously in "real time".
Especially in computer-mediated communication, it is emerging as a tool that can create opportunities for collaboration and support the inquiry process.[2] In this form of communication, face-to-face conversation is not required, and the conversation can last for a long time. It has mostly been useful for online discussions and idea sharing which can be used for learning purpose or for solving problems over geographically diverse work-field.[3]
Asynchronous conferencing has been practiced for many years now in various forms. A variety of means for supporting this form of communication are as follows:[4][5][6]
Asynchronous conferencing allows for the participants to have flexibility and control over the time they spend on any topic. It can allow anonymous participation, encouraging reluctant members/learners to share their viewpoint.[7] Moreover, it allows all the participants to contribute and communicate simultaneously on different topics. However, due to this time constraint, there is a delay between the message exchange. This delay can lead to loss of interest and affects the contextual structure and coherence of the discussion. Sometimes there might be too many posts made in a small amount time, making it hard to figure out the outcome of discussion.[8]
This form of communication provides more convenience. The user can participate from anywhere, as long as there is connection to the conference. This is an advantage for people who work from home, work in different geographical regions or travel on business. Also, the topic can be accessed at any time, and this gives the participant time to think and reply.[9] However, there is a lack of physical and social presence in this form of communication. Especially, in asynchronous text-based conferencing, the lack of presence amounts in a huge difference in the progress and outcome of the discussion. It lacks emotions and is more prone to interpretation error.[10]
One of the more controversial topics about asynchronous conferencing is that the discussion thread might get deleted. This can happen either due to technical failure or from avoidance and loss of interest from the participants. As most threads are managed according to their access time, those threads with older access time might be replaced by ones with new access time.[11]
Asynchronous conferencing is basically divided up into these following types:[12]
This type of conferencing is mostly useful for business and/or learning purpose. Many of the universities are adopting online learning methods and using asynchronous conferencing to manage course-works and discussions.[13][14] It is also used in public opinion sharing or voting through blogs, wiki pages, SMS texting and social networking sites.[15]

Instant messaging (IM) technology is a type of synchronous computer-mediated communication involving the immediate (real-time) transmission of messages between two or more parties over the Internet or another computer network. Originally involving simple text message exchanges, modern instant messaging applications and services (also variously known as instant messenger, messaging app, chat app, chat client, or simply a messenger) tend to also feature the exchange of multimedia, emojis, file transfer, VoIP (voice calling), and video chat capabilities. Instant messaging systems facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list") or in chat rooms, and can be standalone apps or integrated into a wider social media platform, or in a website where it can, for instance, be used for conversational commerce. Originally the term "instant messaging" was distinguished from "text messaging" by being run on a computer network instead of a cellular/mobile network, being able to write longer messages, real-time communication, presence ("status"), and being free (only cost of access instead of per SMS message sent). Instant messaging was pioneered in the early Internet era; the IRC protocol was the earliest to achieve wide adoption. Later in the 1990s, ICQ was among the first closed and commercialized instant messengers, and several rival services appeared afterwards as it became a popular use of the Internet. Beginning with its first introduction in 2005, BlackBerry Messenger became the first popular example of mobile-based IM, combining features of traditional IM and mobile SMS. Instant messaging remains very popular today; IM apps are the most widely used smartphone apps: in 2018 for instance there were 980 million monthly active users of WeChat and 1.3 billion monthly users of WhatsApp, the largest IM network.
Online chat is any direct text-, audio- or video-based (webcams), one-on-one or one-to-many (group) chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs or other online games. Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment. Web conferencing is a more specific online service that is often sold as a service, hosted on a web server controlled by the vendor. Online chat may address point-to-point communications as well as multicast communications from one sender to multiple receivers and voice and video chat, or may be a feature of a web conferencing service. Online chat in a narrower sense is any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email. The expression online chat comes from the word chat which means "informal conversation". Synchronous conferencing or synchronous computer-mediated communication (SCMC) is any form of computer-mediated communication that occurs in real-time; that is, there is no significant delay between sending and receiving messages. SCMC includes real-time forms of text, audio, and video communication. SCMC has been highly studied in the context of e-learning.
Lyceum is a synchronous computer-mediated communication (CMC) software which allows groups of people to speak to one another in real time over the Internet using Voice over IP conferencing. Lyceum was developed at the Open University in the UK and was introduced into language tutorials in 2002. It also offers an interactive whiteboard (for writing, drawing and importing images, e.g. from the Web), a concept mapping device (for taking notes or writing short texts), a word processor (for jointly writing and editing longer documents) and a written text chat facility. The software was written in Java, with some C code to integrate a third party native library used for the Voice over IP conferencing functionality. The use of the software for language learning has been reported at different stages, from the pilot projects since 1997 (Hauck & Haezewindt, 1999, Shield 2000, Kötter 2001, Hewer and Shield 2001), to reports of the mainstream use (Hampel 2003, Hampel & Hauck 2004). Recent articles include task design (Rosell-Aguilar, 2005), tutor roles (Hampel & Stickler, 2005, Rosell-Aguilar, 2007), tutor impressions (Rosell-Aguilar, 2006a), and student impressions (Rosell-Aguilar, 2006b)
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
