Need Help to add signature link on edu profiles

Hi

I have a bunch of edu profiles links which I have managed to sign up to but can't for the life of me find out how to add my signature.

This is how the profile page looks and you will see the link in the signature box

http://ogb.wfu.edu/07/index.php?/member/register

This is the page to register

http://ogb.wfu.edu/07/index.php?/member/login

This is where the problem is. When I login in, it automatically redirects me to this page http://oldgoldandblack.com. It has been driving me nuts and there must be a simple solution to this that works with all expression engine forums.
