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!!!
