I need to force users to register with just their email. I cannot use the Email Registration module, which still sets the username basing on the user name part of the email; in case of conflicts with existing usernames, a number is added.
I have a number of subdomains where I am using the Bakery module; I need to be sure there isn't any conflicting account. The Email registration module will just create a tokenized username with appended unique IDs, creating conflicting accounts.
I imagine that, by forcing email addresses, I can bypass most of this as an issue. How can I completely eliminate the username field and just use the email field?
