That means I am now your fan and that I am watching your auction (F&W) It is basically a status thing I guess lol. It show's that ppl like your auctions and a lot of times like I do, when you are watching it puts your auction on my personal watch list so I don't have to search for it. Hope this helps. I am learning as I go also.
When you list something you can put a starting bid so if you get at least one bidder you will get at least your starting bid. That way you don't have to settle for selling for real low credits. BUT like I said, you should do very very well with that many bra's on one listing! They cause vicious bidding wars lol, you won't have a problem getting a lot of credits! Always make sure you are prompt with contacting winners and your shipping! Everything helps give you a good reputation and feedbacks! And ppl will watch you again and again! Good luck hon!
