Yep I've been doing it. Forgot to sign up the first day but did it easily a couple of days later. I get the surveys at random now.

I have a follow-up question: for those of you that had the second dose, did you have a bad reaction? At my workplace it seems like many have been really affected by that second dose. Mine is due next week. I was able to schedule it the afternoon before my lightest workload day, but if I'm down for a few days that will be a real bummer.
