I want to remove the facebook logo from the registration screen (see attached) so that users cannot register using facebook?

I still want to allow users to login using facebook but not register.

Is that possible?

Hi John,

for register using facebook not only from registration page. at frontpage user still can register using facebook.
when they click facebook button at any pages, and that user dont have account yet at your site. user will get "registration form" in popup.

so if you using facebook button user still must can register using facebook. this is mandatory

Regards

When user registers with Facebook they are unable to decide what their user name will be. That is why I want to prohibit registration with Facebook. Is there a way to allow users to set their username at registration using Facebook?

After they register, I do not want them to be able to change it.

It appears that the second email is not sent with the username if you register using facebook, so there are 2 problems with registering with facebook:

1. User has no control over selecting their username.
2. User does not know what their username is!

Another note:

I understand how this process can work if the user always uses Facebook to login, but it seems to me that they should still have the option of logging in without facebook even if they registered with Facebook. And they should certainly be told what their username is and ideally be able to decide what it will be when they register.

Thank you for your help. Your support has been great!
