congratulations!
You should fill out your profile and your policies page. Also, do you sell from your Myspace page? If so, if you sell the same items, you might get flagged for improper off site linking. If you do sell from there, you'll need to remove that link. I didn't check to see, just giving you an FYI incase you didn't know. Oh, you should put 3 items in your featured area, it looks better
I"d get one of those generic banners or make a simple one yourself (easy to do) until you can get one made how you'd like too.
Good luck!
