ps- why doesn't the [ code ] tag work with BBS tags?

Because it's meant for HTML code, not BBS code. The code could do the logic checks to disable BBS code inside [code] tags, but that would be more work then I'm willing to do right now.

To quote bbs tags, you can do this:

[cod[i][/i]e]

Typing in the above to show the workaround was a pain
