I think it would be cool to have a set of "csf" code for the forums. like:
[code="C#|VB|C++"]using System;[/code] would format the code (to use indentations and such) using the standard IDE colors for types, comments and such. I just thought I'd throw that out there. the current <code> tags spread out the code and make it way too small for me to read (using mozilla).
I might be able to help with this one if you want. I could probably write a class that would pre-process the message block and replace certain blocks with thier actual html equiv formatters. I don't know how your design of the site works, or if a message-preprocessor class would help out. if you ever implemented an edit feature this might get a little more involved. let me know, I'll help out if I can.
