yay a bod mod society! i'm pleased.
i would definitely join

currently have 8mm tunnel, 9mm tunnel, 2mm tunnel, 4mm cartidlidge (stretching is so addictive), lower helix that i think is on it's way out.., rook, tongue web (self pierced, wouldn't recommend it, also on its way out), wrist surface.
tatoo wise, i don't believe in getting any until it would mean something to me. i have friends who simply get tatooed because it's fun, i.e. a friend of mine got a nemo tatoo on his wrist... while it was amusing for a year or two, now everyone just thinks it's sad, including him :P
i am VERY interested in scarification, i have a small S on my thigh, which didn't really scar as well as i'd hoped but it was done a while ago. i have actual scars from accidents that i'd like to cover, so i'm thinking i might get some scarification done.
something else that i would definitely be interested in, if it was easy to find in my area.. (damn living in the middle of nowhere), would be implants under the skin. due to the great health risks with these, you need someone decent and this area, there is nobody :|
this summer i'm going to get involved in suspension although i'm a little scared.. i think the experiences that people describe would be worth it
