RC can be a real problem at the start but will soon become something that you don't ever have to worry about. Once this post pays out you will have enough RC to post at will. There are reasons why the RC system exists though and it is to prevent new accounts from spamming... at least that is the way that I understand it. Don't worry, this is a temporary situation for you.
