Chulie24 - you and I are newbies - I'm still learning the secret codes on this site too! 'GIN' is 'Get It Now', a listing with a set credit 'price' that offers instant purchasing for people that really REALLY want your item - 'long' questions probably refer to the length of the auction listing...just guessing on that one! Hope you're auctions are successful!
Chulie24 - I haven't listed an item for auctio yet, but I'm just guessing that the GIN is something you set up as you are registering the auction..... too much stuff to learn all at once!
