First of all the buyer goes first if he want to, second if he doesn't want to go first just use an OMM: you can add @Riddick, @Busted!, @Flengo, @Symmetrical, @Hugo Boss, a third don't ever say "you go first", like if you were commanding the buyer to go first, that's a typical scammer phrase!
yeah i know for the " go first " that's just a precision for the future ( if there is any future ) buyer , i even post my acc to sell , but i got stoled , i don't know if you understand what i mean because of my english ... I give the acc but i don't get my money . Then i ask GM to give me back . now i'm looking for somebody a little bit more serious than the old one !
