Hello, I can't figure out how to enable BBCode/HTML for Member Custom titles. Ideal would be having BBcodes, but only Mods/Admins can change their titles anyway, simple users can't do this so HTML would be fine too. I don't need images or other crap in it, just so people could use text formating (like color, bold, size and etc). Is it possible at all? P.S. Title grammar fail. :P
