I have the feeling that forum-portlet is buggy. I upgraded from 2.0.1 to 2.0.3 and while an admin user who is member of a group that has a forum can see the forum portlet on my space a normal student who is member of the same group doesn't. so basically no forum at all in dotLRN is visible for students!!!
I wanted to check on the test server but it was always down for the last couple of days.
Can someone verify this bug?
