I can't edit my post

Two problems:
1. My original post got cut down when I tried to post it, it was originally a few lines, but it's been condensed to "<333333>.<;;".
2. I tried to edit it, but when I click Edit Post, it won't change.

So yeah, it's screwed up?

EDIT: Nevermind, it worked. But it still happened, anyone know a reason for this?

adding ">" (usually for the >.> smiley) will break the quote boxes due to how the code works.
