 07-16-2007 #19 Temperal Guest   Posts: n/a What are you talking about? Stickies can't be old? Just because it's at the top of the topic list doesn't mean it can't be old. Speaking of which, I'm unsticking this because it's dead. I've never met someone so annoying as you. Honestly, you should be demoted. Last edited by Scion; 08-23-2007 at 08:57 PM.. Reason: spelling
