Ok, if I click on one of the sub index pages for the forum (e.g. "New Zealand Music" "The Bar") there's something going wrong with the user name links in the "Started" column. When I click on someone's user name in that column it goes to my profile page instead.

The "Last post" column works ok, though. When I click on a user name in that column it goes to the corresponding profile page, just like it should.
