Makes the forum look empty and irrelevant in my opinion. No incentive to sign up, or keep posting. If you do sign up it looks like there's no difference between guest & member and take it from me that people don't ever read all the stickied threads like the admins would like them to. But fine. I'll drop it. But I'm mighty angry!
Only reason it really annoys me is because when I link someone who has an account but wasn't updated, to a good thread or something when one appears, they can't see it. And by the time it gets fixed the thread's not relevant anymore, or the moment is past. You know.
