We do a Officer Drive once a year. This year will be late spring. It's a donation to the site that enters you into a raffle to win prizes. Your donation is good for 1 year and it allows you into the exclusive Officer section in the forum. You will also be eligible to B/S/T and Officer only contests and events.
I'll let you know when this year's membership drive starts. In the mean time, feel free to put up a B/S/T in your signature or if something you need to Buy or Sell right now, mention it in one of the BS threads like the "Everybody Up to" thread.
