@Matt1 : Not received any communication via email lately beyond reminder on Buddy Pass on December 13th, and nothing in spam folder either, and we also purchased the founders edition. So I suspect that if there is an email heading out it will come in due course.
Haven't got one as well even though I am a founder. Could also be that they are sent out in waves.
@GreatScout I'm assuming it's so you can use it as a sound on your phone because it lets you download the audio file.
