Davis,
What the developer mentions is correct. Joomla has a standard Login Page. It's not actually a login module, it's the login view of the Users component.
You can do what the developer above recommends by creating an article with an intro explaining why to register on your site, then creating a 'hidden' menu item for it (a menu item with no menu module published to show that menu). Then configure the SCLogin module to show in a module position on that menu item. With that, you'll have a nice intro area along with the SCLogin module to login using a social network or the standard Joomla credentials.
Besides that though, and much simpler, in the JFBConnect -> Configuration area is a "Integrate with Joomla Login" option. Set that to Top or Bottom and JFBConnect will automatically add the social login buttons to the standard Joomla registration and Login pages.
There's more flexibility with the layout and looks when using the first option, but it's a little more difficult. The 2nd option is easier and may just work for you.
I hope that helps, but if you need anything else, just let me know!
Thanks,
Alex
