I've turn on classified ads (currently with moderation, so I will have to approve ads before they go live) for anonymous posters. This is to allow the just-passing-through the opportunity to post eBay announcements, etc. without having to register. (I'm starting to get requests for this sort of thing, which seems quite reasonable.)

Unfortunately, moderation is an all-or-nothing choice right now, so all ads will be moderated for a short time until I get self-approval working for registered users. I may try no moderation at all but I expect some level of spam posts in that case, so I'm putting that off for a while.

Any opinions on allowing anonymous posts in the forums? There is a large percentage (90%+) of visitors to the site that are not registered or not logged in, that certainly would have useful contributions to make (and probably spam as well.)
