Hi tomato,
If you don't want the store window to be added to your listings, you can disable it at Auctiva -> My Account(tab) -> Settings(Preferences), and it will no longer be added to your newly posted listings.
Once you've disabled this option in your account, you can use our templates and the store window will not be displayed in your new listings.
If you'd like to remove the store window from active listings, you can do so by removing the store window html from the html description of the item using eBay's "Revise Item" form. YOur store window html can be found at Auctiva -> Store(tab) -> Store Window -> Store Window HTML.
Items listed in the Mature Audiences will not be displayed in the Auctiva store window, so, if you only use this account to list in that category, no listings will be displayed.
Yes, you can set up a secong Auctiva account for use with your other eBay ID.
Welcome!
-Mike
