Issues/bugs from this investigation (most just CSS problems):
- Italics and strike-through are ignored
- Super and subscript are just small, not in the right position
- Hexadecimal colors need the hash to work (probably right)
- size=7 was ignored for some reason
- I have unbalanced parentheses ): I suck
- Quotes look just like normal text
- The code tag at the end of the post it's outside of the corresponding <div class="forum_post">
I think I've covered all these flaws...
