I managed to log into Shakenet once using Google and completing the register page with userid, name etc..
After signing out I cannot log in any more.
I choose login with Google and then it keeps asking me to register again.
When clicking Register nothing happens. I See a brief reference to an auth page, but the register page stays up.
This is with Chrome 73.0.3683.103 (Official Build) (64-bit) on OSX Mojave (10.14.4).
My shake is AM.R6B73.00.E[HZ,NZ,NN,NE]
