Welcome!
I just can't understand what the difference is? I didn't mind at ALL being green before I earned my place after 50 posts! Unless someone wants to try and source, there shouldn't be a big reason to want to PM people right off the bat anyway, if you're brand new to the site, how would you even KNOW anyone to PM yet? I just could never understand the big deal! And 50 posts is nothing! You start chatting and getting involved in threads, you'll hit that right away!
Anyway, welcome to BL!
