I really, REALLY hate the format of the MLB.com boards.
this is so much better.
Speaking of formats, I've seen a few PHPBB forums where users have image sigs, and before things get out of hand, maybe a max size/dimension should be given, or better not allowing then in favor of text only sigs might be the way to go. I'm sure someone will eventually try attaching an image to their signature using the BBCodes.
I'm sure most here have seen them, but they eat up space and bandwidth as well as slow down page loads. Maybe disallowing them would be a smart move?
