Set e-mail address as username

Hi,

I would have a registration form like that:

First Name
Second Name
E-mail
Password

NO username

Now, if I make it this way the username is auto assigned as "First Name Last Name" but this way if a user register as John Doe, any other user who names John Doe, can't register 'cause it says that username (John Doe) already exists.

Any solution to let it take e-mail address as username?

Use CB Auto Actions to force Username to Email as shown below.

This won't be an issue with CB 2.0 as you'll be able to select what field you want to fallback to for Username.
