I found the answer to my question on another board..
Here are the instructions in case anyone need them...
"It's also not really clear how you cash out so let me explain that one, too. There is a cashout button. When you click it, the details of your balance are there and there's a comments section. In the comments, type in how much you want to cash in and put your CreationsRewards email in there (if you want to cash in for CR points, that is!). That's it! You just have to be kinda specific because if you have $2.00 in QR earnings you might only want to spend $.75 of it on CR points...he wants to be sure to give you exactly what you want."
