There is a way to do that as well.
Ubb code can be used many different ways, it would just require adding some coding to that specific Field much like the Signature field.
If I get time I can figure it out and let ya know.
Oblivion Knight: That is very much possible, at the normal moment html and ubb codes doesnt work in that field however if could be change and added much like the post color, and that I have included in that hack. But just by using if codes and if else like I did to trap and use the codes it could also limit what is avalible.
