2016 Race license



When can I sign up for my 2016 race license? Its looking less and less likely that I will be making either of the last two races of this year, and I want to retain my number.

I did my NRS at Sonoma, and want to try to attend as many races as possible next year (putting in my bid for the novice 450sb championship!) So when can I get my 2016 license?
