I don't seem to be able to find general rules/ procedures/ guidelines for selling stuff. Can someone point me in the right direction?
Bill,
It looks like it's set up just like the old Classifieds that were here in the past...
For selling, simply add your post in the Classified section with whatever information you like and then just keep an eye on your ad for requests or replies. For shopping, just check regularly and either reply to the sellers post or send a PM to the seller and the early bird gets the worm. Payment options can then be agreed to within the two parties. It's very quick and easy. Personally I prefer it because I think it's much easier to do simple "one-on-one" transactions, just my opinion.
