Blackboard courses support discussion and document sharing. The service integrates bulletin board, chat, white board, assessment, and document sharing in a single web site. Each class member uses a personal account to login and use the service.
Email lists support discussion.
Using a single email address, someone can send a message to all members of a group and a reply would again be sent to all members. FirstClass supports communication and file storage. It is a bulletin board system with integrated web, email, chat, and file servers. Individuals can access their FirstClass conference using the FirstClass Client application and web browsers. Streamed media includes audio, video, and animated presentations that require very little waiting before being viewed.
