You have 411 credits right now. If you look to the side where your avatar is being shown, it says it at the bottom. If you click the shop button at the top of the screen, next to chat and members, it should also be at the bottom of the list that appears upon clicking. If you click the credits shown, you will get a popup showing how much credits everyone has.Wait... how do we know how may credits do we have?
Heck, how we do earn credits? Do we have to work on something?
