I have listed 3 items that were removed too many times how do i delete it completly from the mp, error msg for this is: Removed under our Marketplace listing guidelines for Item Not As Advertised-Incorrect Listing Category. ALSO how do i delete the whole store without removing each item individually?

if you start a group so it says you founded the group. is there a way of shutting it down so it no longer on secondlife?
