Well, hey, nice to have you here. It's always nice to have a new member to our own little family, although I say little when there are over 3,000 members here on this board. If your new to the whole forum business, although it doesn't sound like you are, there are some Links you should check out, here are the two main ones we want you to check. The Forum Faq if you have any questions. But if your question is not answered don't hesitate to ask in a Private message or something. You can contact one of the staff here, easily, as you probably know by now. The other link we want you to check out is the Rules.
Although you probably know half of this, from scouting around the site for about six months as you said.
If you need a Sig or Avatar or both, please don't hesitate to check out the Sig and Avatar requests thread. You can request anything you want, as long as it sticks within the rules like dude.
Well, anyway as you can probably see and guess from my username, my name is Steven, and nice to meet you dude. ;) Have fun here.
