I seem to be having problems with the forum. When I post a message it doesn't seem to always appear properly. They seem to right away, but once I exit that thread I've noticed my name doesn't appear to show up as the last person who posted a message.

Also, I see that people have signatures, but I don't see where I can create one. How do I get one to work? I feel like a goof at the moment.
