Ken what I say about the reserve and reslimit fields are true and is backed up by fact. Look at the classifieds code. Everything I have said is backed up by the code.
The only fields that have any point in this discussion are reslimit and price. I have already tested what I have said before I even post. If I enter a reslimit say of 100.00 and put a price of 25.00 and then I tweaked my database to set my enddate less than right now. I run the cron and low and behold my auction is renewed for another duration. Proof right here test ad - PhotoPost Classifieds
As I have said if the price is below the reslimit the auction the notification emails for highbidder and to the seller would never go out. If your getting emails that your auctions have ended and the highbidder is blah blah blah then the price on the ad has to be more than your reslimit.
