It seems that when you have the [list ] BBCode tag near the beginning of a post next to an avatar, it doesn't seem to be displaying correctly. The dots appear inside the avatar. I looked at it on Safari Version 4.0.5 (6531.22.7), Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:18.104.22.168) Gecko/20100315 Firefox/3.5.9, and on Google Chrome 5.0.375.55; and none seem to display it correctly. For probably obvious reasons I don't have IE to test it on.
The thread where I'm seeing it is here. Not a large issue by any measure, just thought I'd bring it to your attention.
