The structure consists of folders and discussions. Folders hold the discussions and help to limit access to them if needed.
Discussions are where the participants actually leave messages for one another.
The host has the ability to 'moderate' the list so she can read each message before it is posted or, since this impedes the process in most cases, the host can opt to allow all messages to be posted and then simply exercise the right to delete inappropriate messages at will as necessary. Participants can delete or edit their own messages for up to 30 minutes. They cannot disrupt any other participant's posts. There are areas where guests can post and area restricted to only registered participants. Currently student groups, Faculty, and Staff are allowed to request that a folder be set up for them, their class, or their project.
