I agree with what is being said here, also. If eBay was bumping folks that use Auctiva, to the bottom of the heap, then they'd be bumping one heck of a ton of folks.
Also, realize Auctiva knows a lot more than even we do when it comes to making our listings fully happy in the eyes of the ebay sorting engine, so Auctiva will do everything possible to make the Auctiva features fully compliant.
