Border around avatar and postbit information...

[RC Attacker]

Can someone help me put a border and background around avatars and postbit information, exactly how it is on TeamXbox (and also center the username and user title)?

Colors and pixel width don't matter, so I guess it could just be a black border with a white background and any with for now. That, I can always edit later.

I have this on one of my forums and when I tried to use the same thing on a different forum it wasn't working and I'm not sure why.
