Guys,
Some good ideas here.
Re: custom forum buttons. I don't see a way to do it, but it's a good idea. I'm not a good graphic designer, so I wouldn't be able to make new buttons.
Re: red text color. Yeah it sucks. I don't need my name to be in red, thanks very much!

For some reason, they didn't use CSS for that- it's done somewhere else. Anyway, I'll find and fix it.
Re: the big white balls - you're right, the old buttons had dark backgrounds. I can't remember where I got these - i think one of our forum members fixed them up for us. I'll attach our old buttons here for reference.
No, it's not a contest, I was just hoping for a little help on fixing up the buttons. As I said, I'm not that good at graphic design.
Also, there's still lots of little tweaks to the theme that need to be done - like the orange-on-white "Tip" in the posting window, the red-on-green text, etc. I'll fix them as we go...
Cheers,
-John
