Button art guidelines

This site strives to be "family friendly" and "safe for work", and currently uses US norms for this, as most players are either in the US or in places with less conservative standards. Our current guidelines are:

• No nudity below the waist.
• No female frontal nudity above the waist.
• Nothing explicitly sexual in any event.

(The US gender bias about toplessness is controversial, but we would rather make the site more appealing to more people, and not use button art as a venue for taking a stance on the issue. There are plenty of other places to do that, if anyone is so inclined.)

Also, if anyone finds a piece of button art objectionable (whether they're on the dev team or not) and complains about it, we'll take that seriously, discuss among the dev team, and figure out what's best to do.
