Besides the bold and italics buttons just not working, these forums have lots of other problems. Quote someone and start typing your reply under the quote and you can't separate your reply from the quoted content - the quote button just won't do anything. Yet editing the reply after it's been posted will allow it.
Also, think of how hard it was to add avatar images, signatures, and such. Way harder than any other forum. And when I try to input my personal details into my profile, it always gives me some error message.
