When I go to the "Edit your profile" page, the Username in Account Information changes to "New User".
Everytime I switch the "Show Other Users Signatures" to YES and apply changes, it gets immediatelly back to NO. Most of the signatures are visible, though, but some of them aren't.
The last is that I don't se my signature in any of my posts. It's not so problematic (might not even be a bug), but I'm kinda used to see it, too.
I've tried to clean cookies, restart browser (Firefox 3.0.10), even restart the PC. Nothing helped.
