Now, I'm not real good at this kind of stuff, but here's some tips:
Use the search function before you make a thread. No one likes reposts and they'll flame you for it.
Use the edit function if you want to add to a post you've just made. No one likes double posting and, again, they'll flame you for it.
Post in the right sub-forum.
And most importantly of all, be smart, abide by the rules, and be a contributive member!
Welcome to GTP Infinity_Master.
Just like everyone said, read the AUP, bla bla bla bla bla bla, watch out for Famine, bla bla bla bla, don't get in trouble, bla bla bla bla bla bla bla, and also, just try to have fun here. We won't bite you.
Welcome, and I wouldn't worry too much about Famine, he once told me off when I was new, since then i've had a posting complex and have tummy movements when i see he has posted in one of my threads, but other than that AUP as mentioned and have a good time.
