I didn't get a registration email, even though clicking submit gave me a message saying to complete I needed to confirm through getting the auto generated email....
But just used the password I set and it let me log in.
Brilliant! well that was a pretty easy fix. Interesting that the username & password I tried the other day wouldn’t work, but the first one I set up did work. I did try with that first one as well (and it didn’t work) so maybe there were some changes made since now it does?
