There is so much to teach about isn't there?
Today teaching isn't only about giving lectures and transferring know-how from the lecturer to the student, it can mean reaching a learning goal together. For that, collaboration can be facilitated in OLAT by the use of a project or a learning group. You can provide files with the Folder, enable a discussion Forum, work together via a Wiki or a Calendar, communicate via E-mail or the Chat, and collect your work with an ePortfolio.
The latter can be accessed via each users Visiting card, but only for those entries which are open to other users. Additionally each user has a folder in his Home to share documents in a simple manner.
All the above mentioned collaboration elements can also be provided through a course.
