Can I just make a quick suggestion:
Maybe you should try changing the code for the U2U link in the header to this:
Code:
<a href="http://www.thisisbigbrother.com/forum/u2u.php" target="_blank" onclick="window.open('http://www.thisisbigbrother.com/forum/u2u.php','Big Brother UK Forum','width=700,height=450,resizable=yes');return false;">U2U</a>
The difference in that code from the existing one is, for those that don't have Javascript turned on or have a pop-up blocker, the U2U link should open in a new tab or window, and for those that do have Javascript turned on, it will appear in the pop up...
