A2: Sign up for listening tests

Progress on Architecture A2 has been coming along well, and I'm pretty happy with the results that we've gotten out of Stage 4 of the work (optimizing A2).

With that, development will enter the fifth and final stage soon: listening tests. If you haven't already, please sign up to participate by filling out this Google Form. Please also share it with people you know--the more responses we get, the better I can understand how A2 is doing!

Thanks for your patience; I'm really excited to share what's been developed!
