Yeah, the rating stuff is kinda weird, so I feel you there. Usually people around here just need to get familiar with you to feel more welcoming of your presence. Do you have any pics of you or your g/f or friends? If so, post those up, as that usually helps people put a "face with the name" and makes things more hospitable, you know?
I think everyone is just messing around with you about the "we hate J-body people" stuff. Actually, they're quite well liked here - hence why there's an entire section devoted to them. You'll really like it once you get there. The moderators there - Rad Ronnie and Faggy McGee - are really knowledgeable about the J-bodys and are a lot of help with the technical stuff.
Okay, dude, so, get to posting those pics and join the party already!!!
