Whenever I post in the new in-game forums using IE, it considers my input to be html formatting logic (a resulting behavior being that very little implicit formatting is done on my input) and thus allows me to plug html formatting directly (with tables, columns, rows, styles, etc) into the game (no JavaScript though, good catch :P).

Whenever I post using Firefox, it considers my input to be text and formats it properly (and of course displays any html formatting I put verbatim without doing the actual formatting).

I would venture to guess that the Firefox behavior is definitely the desirable behavior here (besides I can't make in-game javascript forum tools with IE anyhow and even if I could, allowing users to insert javascript into the forums would be a security hazard) so perhaps it should be made to be the IE behavior also.
