I think I want to give it a shot.

I've been wanting to shoot a match for a couple of years, but haven't had the chance because of work. I plan on attending the match in September at Magnolia. What should I expect? Are new shooters allowed to just show up and shoot, or is there a training/orientation requirement? If so is there a scheduled time? I used to watch every now and then when I was a member of magnolia, but never got the nerve to compete.
