I came to think about something. We we discuss things here in moodle and have meny different forums. Then you get subscritions on the forums. But after a while its tricky to know what forum you subscibe on and you have to go to each singel forum if you wanna unsubscibe. Is it possible to maybe under the user profile have a listing of subcribed forums and make it possible to unsubcribe there ?
Take a look at the right-hand column on http://moodle.org/mod/forum/index.php?id=5
