Well, while we're at it, theres a rather serious bug with the html tag parser -- or rather, it's completely functional, apart from the fact that it's not an html parser at all. If you write <em/> it won't convert it to <em></em> like it ought, and browsers don't parse the resulting page "correctly". I've tried it with firefox, opera, safari, and msie, and they all end up making the whole rest of the page italic. Same goes with <strong> and so on.

(And there really should be <code> or <tt> or something in the allowed html tags list.)
