Nevermind, I found the rules section. Selling (even personal trades with members) aren't allowed. And I didn't intend to infringe on the rules with my post; I just wanted to give a full description of what I wanted to do. It's easier to give an answer when the question is fully detailed, and I don't think it's the same thing to post an advertisement as a commercial business as it is to post a small notice as an independent, not-for-profit hobbyist. The rules state that no selling of any kind is allowed, though, and that doesn't leave much room for questions. Thanks.
