I’ve yet to receive any emails. I never got one for when I signed up, when it started, for continuing, nor completing. Although, I did have the first course done previously, so maybe that’s why? I did retake the first course unlocking the Journeyman badge, and have completed all the required courses unlocking all the badges.
I’m just posting here in case it’s not expected behavior. I don’t want to miss out due to some emails not being sent. I definitely signed up with the correct email too, and I’ve checked spam and all that.
