Thanks for helping me then, I shouldn't be complaining here then.

I got rid of all the extra fields, bio, etc... so nothing was being imported.

But I still get registration form with just their email filled in and their name (with a space between first and last name)

So a password is still needed
click to agree to terms/etc..
my capcha

Is this how the FB login works, just imports the email, no photo/etc?

If you go to the registration page, you will see a full registration form. If a user just clicks the little Facebook icon in the Login dropdown, they will get a popup window and be able to simply click to login via Facebook. But, as Zachery says, they will get logged using their REAL name and not have the option to change it to some other username.
