Sure, I'd really appreciate it if you'd let us know know a bit more about the flaws you encountered with the registration process (other than not being able to choose your username when joining with Google/Github).
What happened is that I signed up via Google and, of course, I couldn't create another account with the same email. Then, I logged in back with Google and changed the email. I got no message that my new email is pending verification and shortly I got an email at the new email. So, I clicked on the link in that email and verified it. As I didn't have a password, I logged back in with Google, which created a brand new account (nikolaynkolev9). I logged out and tried to reset the password of the one I verified right before and was told that this email does not exist in your system. Very weird design, honestly! Given I already created another account to get the desired username, I ended up creating 3 accounts.
