BTW not to be picky but its Xbox LIVE not XboxLive. Also I think you should call it Xbox LIVE cause it seems more general so that if you later add more functionality that goes outside of just Friends your app name will still mean what the app does.
Also I dont know if you have an icon yet but this would probably be a good image to shrink down and make an icon out of. If you want I can make you an icon in a couple of days.. im in my second house and the PC here is garbage and doesn't have Photoshop so that's why I said "a few days".
