Discussion Boards – UMaine Machias
A discussion board (or forum, bulletin board, message board) is an online tool that lets folks make posts and/or comments on other folks posts. Sometimes you need to be a member to make posts or comments.
Often there is a central unifying theme or topic that provides an environment for discussion, with many posts and responses. A post and the responses are a thread. A discussion board can have many threads, sometimes separated into discrete topics.
One of the advantages of a discussion board is its asynchronous nature, allowing people to post or respond without any time frame restriction. This is obviously different from IMs or live chat.
