You're in, you clearly fit these requirements and the Cows, obviously, smile upon you. You are currently a "Mud Grunt" by rank. Now the good bit: you can officially put this template wherever you want on your userpage or talk page and can add "Mgr." to the beginning of your signature, if you wish.
Promoting the CMC is always good, considering at the moment we're barely even tiny on Uncyclopedia. If you can refer users to sign up, consider yourself promoted. In time you'll move up the ranks anyway. Occasionally you'll have to put a little bit of work in here and there, but only a little bit... For the moment all you really need to do is watchlist this page. Your main task, however, is CONVERTING THE COWLESS. Have a quick read of this before you start and conversion processes. If you help swell the CMC ranks, it's likely you'll get a promotion!
I'm happy to answer any questions here. Oh and it's advised you read these (loose) rules. You are now one of the few with the Cows on your side.
