Regardless of whether a signature is nude or just "semi-nude", we're going to take a poll and decide whether these signatures are to be disallowed from the site. I've come across countless PM's and other kinds of complaints to these kinds of signatures, and I'm just going to let you decide.
It's a forum, after all. This forum is a forum for Knights Online, and not a porn forum. Honestly, those who look at half-naked/naked women all day have really no lives, and are simply fantasizing about something they know they can't have.
So, vote on the poll.
It will take a 66.67% majority vote to have this in effect.
