lt. thomas - your best bet at this point is to enjoy your involvement with the community and just have fun on the servers. Promotions are handed out as a sign that we trust you and feel you are mature enough to handle the responsibility of being an admin. The best way for us to learn that about you is to see you in the servers and around the forums.
My suggestion to you is to not worry too much about getting a promotion...in fact fishing for one is probably one of the worst things you can do. Just play, have fun, learn the community, and in time I'm sure we'll see you with a new letter added to your tag ;-)
