Hello!

My old signature is still coming up on the forums, even though I've since updated the information in My Profile to show a different one.

The new signature shows on the my profiles page but it doesn't come up when I post.

I've had the same problem. It takes upon a day before your new signature shows sometimes, even though it's there in your profile.

More strangely, I had my new signature show at home and my old one showed up at work. Both computers had their temp internet files deleted.

Woot for bugged forums!
