JFBConnect doesn't have it's own login page, we just have our SCLogin module. Additionally, 3rd party extensions don't have a good way to force the user to a specific login page, they almost all build their own (which is really why we didn't want to build our own and complicate matters further).
With that said, there's a few good options that should get you going:
* In the JFBConnect -> Configuration area, configure the "Integrate with Joomla Login" setting. That will show the social login buttons on the standard Joomla Login and Registration page.
* In EasySocial's Facebook Connect configuration area, enable the "Integrate with JFBConnect" setting, which should show our social login buttons in their login forms.
I hope that helps, but if you have any other questions, just let me know.
Thanks,
Alex
