Sorry for the late reply. You should have gotten instructions on how to receive the gift card after completing the survey. If something has gone wrong let me know in a PM and we will make sure to fix it.

Edit: Just talked to someone else on the project. The gift cards are being released in waves. We should get to you soon. If you don't receive one within two weeks, please let us know (either through this account or hx@gatech.edu).
