Welcome to the forums! We have greeters for this "Rules" part, but I'm the only one online right now so I'll go through it with you. ^_^
Be sure to read all the Rules. Most are common sense. Be nice, have fun. We don't bite. =) Rules are at the top of each forum. Here are some important ones to read for Newbies, but like I said, it's all very basic stuff:
Information for newbies
FAQ, Tutorials, and More!(Updated 21/4)
Spam, Netiquette And Basic Forum Information
Like I said before, have fun!
