YES!!! ME ME ME!! I have been having trouble like that!! I doesn't seem like I can log in, even after trying 25 times, so I close my page, then come back on...when I get back on, it know's I'm here, so I was truely logged in, but it just didn't show my avator...
..and the post thing...that just happened. I replied to somebody's thread, but when I went back into that section, it wasn't at the top, nor did it show my post as the last one..so I went and posted agian, THEN IT WAS THERE!!!
It must think I'm a ghost!!

lol
very very strange....
