You can join a Google Group without having a Google ID, but it's not very apparent, and I end up having to search for the instructions every time that I do it. This is an attempt to codify it so that I can 'set it and forget it.'
After running this command, the sign-up process will be initiated and Google Groups will send you confirmation email.
