There are 5 forum types:

* A single simple discussion - A single discussion topic which everyone can reply to (cannot be used with separate groups)
* Each person posts one discussion - Each student can post exactly one new discussion topic, which everyone can then reply to
* Q and A forum - Students must first post their perspectives before viewing other students' posts
* Standard forum displayed in a blog-like format - An open forum where anyone can start a new discussion at any time, and in which discussion topics are displayed on one page with "Discuss this topic" links
* Standard forum for general use - An open forum where anyone can start a new discussion at any time
