Okay, I see the problem.
For one, the link is wrong... it should be .com, not [/i].con[/i]. Secondly, if you click on someone's profile, it leads you to 'http://armorgames.com/user/username/', which for some reason whenever you click on a page at that point leads you to 'http://armorgames.com/user/username/username/#' instead of 'http://armorgames.com/user/username/#'. That's probably because it looks for the last slash and changes the link to 'username/#'... So when the link is 'http://armorgames.com/user/username/' instead of 'http://armorgames.com/user/username', well, I suppose you can imagine what happens.
