GIN will be allowed to you when you complete auctions with 100% feedback. Takes time :) I would recommend using real photos you took with your user name written on paper beside your auction.It helps people feel safe with bidding. Credits are hard to come by and people hate working hard for them and getting ripped off.
*also another thing when someone asks questions to you hit the reply button under the question,this way they will be notified you answered them :) I didnt even know you had wrote back to what i said before because you just wrote to your on questions :) Mobile Listia is Just alittle different from computer,can get tricky.
