Welcome to the site. You will come to find a good plentiful of friendly faces around here, and so long you don't post any faggotry on the forums, nothing bad will happen.
You will want to talk with End_Master, pretty much the iconic face around here. To summon him over, you tag him (@[Name] ) 3 times in a row - that's kind of like his code for a new person.
Best of luck!
Oh dear, it looks like I posted twice by accident. Can someone delete this please?
