RFC: newmember list policy?

Question: Anyone can join the list (cctalk or cctech) without moderation, automatically. I was wondering if it might not be good to require an email you will. Something to give them an opportunity to say what they collect, what type of systems they are interested in, that kinda thing. This would serve two purposes. First, this email would be forwarded to the list as an introduction to everyone (not for a vote or anything like that). Second, it would give me a fairly reasonable way to make sure people who join the list are real collectors, or people with a real interest anyway, and not some schmoe wanting to post ads for modern equipment, or harvest list addresses by receiving the traffic. Sure this is not a fool proof thing, but might help alleviate that. In addition, I was considering no longer allowing posts to the list (cctalk) flagged for moderation. However, this is taking more and more time of mine to read and approve (reject most) of those. Thus, I was considering making someone join the list before they can post at all, even with moderation of their posts. The downside of this, is on rare occasion, someone (not a collector) posts to the list that they have interesting equipment available, and I don't want to have to make them join the list. Their post would be silently rejected. This doesn't happen often, but who wants to miss a real gem. Please email responses to this directly to me instead of the list. Jay West
