I would like to allow my users to register with out providing an email address. Ever! My reason is that if you require an email address on a children's website then you are required by FCC rules to notify their parents. By not collecting any "identifying" information you can avoid this.
This topic has been brought up before. See:
Although there is a hack to not send the users password to their email address, I haven't figured out how to completely remove the email address box from the registration page. Also, when the new user registration is verified a check is done to see if the email address is valid and unique.
I am new to Drupal and would appreciate any advice. I would prefer not to modify the core. Is it possible to do this in a module? Ideally there would also be an option in the admin pages to disable the email requirement. I would be glad to write a module if this is possible. What hooks would I use?
