Welcome Cristal and Debbie,
I'm am still fairly new at this shopping thing but having fun in the Phoenix Area.
This is a great place for starting out as everyone is very helpful and site is really set up well to guide the newcomer.
As the others have said, the badges are a quick reference for schedulers to aid them in assigning shops to us. They are very busy people
so i'm sure it works well for them. It's also kinda nice to find you have received a new badge after completing an assignment, like an extra reward. :)
Have fun out there and please ask if you have any questions.
