A discussion is essentially a discussion forum where you can post questions, answer others questions or engage in conversation and debate.

The structure of discussions are as follows:

1. Forum – this is the headline subject for the discussion
2. Discussion – these are individual questions or posts within a forum
3. Replies – these are individual replies to topics

Providing you are a member of a group, you can post in the relevant discussion forum related to that group.

You cannot create a new forum, but you are able to create a new discussion within a forum or reply to any other discussion.
