I spent some time looking at other interest-oriented discussion boards I frequent in home shop machining and other interests (woodworking, Whaler boats, John Deer garden tractors, classic Cadillacs, classic Triumph cars, etc.). About half have no classified section, and on many no advertising or posting of ebay auctions is allowed. Those that have classified sections all have rules, some more restrictive, some less restrictive than what we have here. All restrict use of the classified section to registered users, several ask that only active members list items for sale. Most ban posting of ebay auctions until after the ebay auction ends. One of the rules I really like is requiring for sale ads to list a price, so that it doesn't turn into an auction with members bidding against eachother, which causes hard feelings and flame wars. The rules here may be a little less clearly defined than most other sites, but it's a great site, and a lot more civil and friendly than most. The owner is paying a lot of money and spending a lot of time to host the site for our benefit, and the owner should be able to set the rules. Yeah, there are some commercial ads on the site (which most ignore) but more often than not, on interest oriented sites, they don't cover the costs. There are ads on television too, but that doesn't give viewers the right to dictate what the station broadcasts.
