I have UBB 6.0, Beta 7.8, which you can see here:
http://www.nintendonation.com/cgi-bin/ultimatebb.cgi - It works absolutely fine.
However, I have ONE member out of 1600 complaining that he doesn't like the login-logout system because he doesn't have cookies enabled. So now I look like the bad guy because some baby can't have it the way it was.
Um, but, anyway. Is there any way to remove this login-logout system and use the old UBB method?
