From an email (thanks to valued commenter and tester M. Bouffant):
Hey everyone, WaterGirl here.
You are receiving this message if you volunteered to test the new website and supplied information about your devices, but never followed up by sending email to [address deleted]
I am starting to get our ducks in a row for whenever testing will start.
Please write back to [address deleted] — one way or another — to say that you’re in for testing or that you don’t want to be contacted about testing again.
Hope to hear from all of you one way or another, very soon!
