Just to add, I have already done this
but the "buy it now" link still shows on the advertisement.
Would also like to remove the "Remove “If this is an auction you may enter a reserve price to allow users to buy the product and end your auction. (Numbers only!)::” option from showing at all.
Lastly, would like the default option for "Want to be notified by email when users post replies?" to be set to yes.
