Before we can sent out the surveys to everyone, Backerkit requires a 'smoke test' where they send the survey to a small percentage of backers across all pledge levels. This gives us a chance to make sure everything is set up correctly and fix any mistakes before sending the surveys to everyone.

So, if you got you survey today; congrats! You're part of this smoke test!
Everyone else will get their surveys once the test is done and any issues that need fixing are fixed. Probably a day or two.
