The SCLogin module doesn't perform any registration functions. When you click the "Register" button, the user is redirected to Joomla's standard (built-in) registration page. We don't have any control over that page.
To answer your question a little further though, Joomla currently requires an email address for each user. I believe there are plugins that disable that requirement, but I don't know of any to recommend off-hand. Additionally, just so you know, when you disable the email activation requirement, you are opening your site up to a lot of spammy registrations. There are other tools out there to help minimize those as well and it's not something that should prevent you from doing what you're looking to do, but something to be aware of.
I hope that helps, but if you have any other questions, let me know. We'll try to answer however we can.
Thanks,
Alex
