The sticky is a compilation of all the advices usually given anyways... the guys mean no harm, but you really should just head on over and read the sticky (everything tends to be repeated and repeated and repeated, over and over, and over again)

welcome to the forum and welcome to the sport!

If you really want us to give tips here:
follow the laws, be smart, be safe, be respectful. have fun with it, and you'll enjoy it. Your ass will hurt at first, but you'll get used to it. if things are hurting, get a good professional fit, and you'll hopefully keep from hurting yourself.
