Guildlines For Applying  You must be over 18 to post any sexually explict, suggestive, or "erotic" material. Anyone may post pictures that are artistic, tasteful, or similar.  This is a rating community, expect to be rated.  Follow the application requirements carefully, and try your best.  Put all apps behind the appropriate lj-cut.  You can reapply once. (In addition to challenging.)
Guildlines For Members  Be active. Show some interest.  You may promote here (under a cut) but you must promote this community 5 times somewhere else and show a link to each.  Judge harshly, don't accept everyone. Judge on art, style, sexyness, attractiveness, beauty, the app itself, or whatever.
Guidlines for Challenging  Any reject can challenge any of the first 35 members.  Post pictures of yourself, and say clearly what member you are challenging.  Whoever gets the most votes, is accepted and the other may reapply.
