register and start earning FREE gift cards and other prizes by filling out surveys.
Once you do enough surveys get the Ultimate Game Card (UGC) to receive your CE.

Tips
You are going to get tons of spam after filling out the surveys. To counteract this a second email address is recommended.
To fill out the forms quickly use an auto form filler such as Autofill Forms, a free add-on for Firefox.

I personally guarantee that this is not a scam as your spiral knights username and password will never be asked of you.
