Well, spam has become bad enough I've decided I need to do something more to help prevent it. So, from now on, you'll only be able to post at the Orchard if you have a registered account that has been approved for posting by me. I'm slowly going through and approving the existing accounts that I know are legit. If you are a new user, or if you'd like your account approved right away, PM me and I'll approve your account.
(Approved persons will appear as "staff" in the board statistics, but they won't have any special powers beyond being able to post.)
Hopefully this all works how I think it should. Let me know if you experience any problems!
