How to use HTML in names and titles.

Titles: Open up common.php and look up the function get_title. Replace "$user_title = htmlspecialchars($user['title']);" with "$user_title = $user['title'];"

Ranks: Same as above but replace "$user_title = htmlspecialchars($value[0]);" with "$user_title = $value[0];"

I think that'll do it.

Allowing HTML in usernames requires a lot more editing since it is printed out in many different locations in the code. I don't thinks it's a good idea anyway considering that users select their own username when they register and if they register with a username such as </table>, the layout of the forum will be screwed up.
