Good intentions Heath. I agree with most of what's being suggested.
Well since the other rules are basically self imposed, how about we all impose a post requirement for first time sellers? It isn't something which requires moderators to monitor. We could all decide on a reasonable post count(with more words than a few or a picture) that we'd like to see first. The probation list is something that we self police, board members speak up when somebody from the list jumps into the marketplace. Why not do the same thing with a minimum post count. Say 100 is needed to sell here, then assuming normal posts are made, people will get at lest an introduction to how new members think.
It still is somewhat like eBay, lots of people don't buy from low feedback new members. Regards,
