Can you race unoffically until enough experience to establish a rating?

Not that big a deal. I would not worry about it. Being up front it all it takes. Try your rating out. It will take awhile for you to get a feel if the rating is even an issue. If anyone has a beef, just be willing to adjust is all. Typically the ones with a beef that can't be reasonable in discussing... probably know less and are more in the dark than you...
You are on the right track.... <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
