[support] site with no email requirement

i tried posting on the forum but nobody has replied yet. so i am repeating my question here. how do i set up my drupal site to not require an email address? my users are not very computer savvy and i don't want to have to require them to have an email address. not on the registration page and not in their account page either. please help. i tried the logintobogan module but that does not seem to have such an option. thanks nick
