The invite friends is a module only. No dedicated page for this. Right now, the way to create a page specific to that is to create an Article, put some text in the article describing why the user should invite their friends, and then placing the module in a module position on that page (generally below it). This is the best way, in our opinion, as you can then hand-craft the 'surrounding' content to try to ensure more invites to your site. The above is what we do on:
facebook.sourcecoast.com/jfbc-invite-full-view
There are no other 'pages' contained within JFBConnect that you'd want to link to. The Login/Register page is only shown if the user clicks the "Login With Facebook" button and is registering.
If you have different ideas on you'd like it to function, or if you'd like the JFBCInvite to be it's own page, let us know and we can investigate the different options.
