That is the incorrect URL. It sounds like you have a 3rd party extension that is incorrectly altering the URLs for JFBConnect. Please go into the settings for that SEF extension and disable URL creation for JFBConnect. All SEF extensions generally have a way to prevent URL creation on a component-by-component basis.
, the first page it sends me to is "/index.php/component/jfbconnect/#"
Currently, we don't have the ability to assign users to a different group. They are all put into the default user's group (usually Registered). It's not a highly requested feature, but we have plans to add a user-group option in a release in 2016.
As an aside, how do I choose with User Group these newly created users fall into?
It would be useful to be able to say "Logged in using Facebook? OK, they're group 5" or "Signed in with Google+? They go into group 6".
