Congratulations, jenn1, and welcome to the myFICO and Disco families!
$10000 is an extremely nice SL for Discover. Very nice!
Be sure to take advantage of the 5% cashback categories, and the cashback match after your first year. It can really add up! Also, they have a Discover Deals that you'll see when logged in to your account. On there, you can often get 5% or even higher cashback at certain Websites or stores. It's worth checking out.
