We changed the way VAPS links to the forums to get around a security block that resulted in not being able to use the vbulletin admin functions on a user account. Although the VAPS profile page included the bug fix, the game list page did not. It's been fixed now.
Just go to your VAPS entry (profile or list of games, 'save' anything, even no changes on the VAPS profile page) and the links should reappear. I just tested it myself.
