Okay I've had someone contact me that they are having a hard time creating an account on a desktop because when the "enter your email address" sign up window switches over to "enter the six digit code" it reverts back to "enter your email address" when you go to check your email. I signed out and had the same problem. Hopefully there is a real fix to this but in the meantime I've found this to work.
Have the forum open in one window and your email open in a separate window (window not tab) which is also visible
Enter your email address in the pop up
Leave this window open and in the foreground. The six digit code is in the email title so you should be able to see it without having so switch away from the forum window.
I've tried if a few times and it worked for me.
