Hi @bdarla! Thanks so much for the kind words. 
I’ve been (slowly) working on two new courses – one on TDD Phoenix and one that’s a crash course on Elixir/Phoenix/Ecto.
I’ve been a little slow on the work because I’ve been putting time into PhoenixTest.
But I’m hoping to keep moving with those courses. And once I’ve done the prep for them, and I’m ready to record lessons, I’ll let people know where they can hear more about those courses!
