Joe,
No problem for the support. It's what we do, and why we charge for a subscription. We realize Facebook integration is always a moving target for development, and has special requirements for each user's site.. and therefore, needs a high level of support. Without it, JFBConnect just isn't a great extension (though we try to make it so you never need support...)
Definitely understand the JomSocial convention, and realize we don't adhere to it completely. The reason we only show required fields during the "Full Joomla User" process is simply because the admin has deemed them 'required' (i.e. minimal amount of fields that need to be filled in).. and one of the benefits of JFBConnect is a 'quick' registration process.. which is why we focused on those only. It's definitely a disconnect as you may want more fields during registration, even if you don't need the info, but admins that use JFBConnect generally are trying to use it to minimize the registration flow. While that should mean similar requirements for Required and Registration fields, that's not always the case (we think it should be, frankly).
With all that said (yes, I like to talk), if you're using the "Facebook User Only" setting of JFBConnect, really none of the above applies, since only what you map is what gets imported. As for the registration page from JomSocial, there's no way to redirect to that page. The user information isn't stored permanently at that point, only in a temporary state while more and more information is added to their profile. Once the registration profile page is complete, JomSocial actually stores all that info in the database. It'd be really difficult (and JomSocial version dependent) for us to implement support for using their view to do that.
We could easily help you to change the "Full Joomla User" registration flow to show all registration fields though, in case you'd like to do that.
So.. hope that makes sense, and explains where we're coming from, even if it's not exactly what you're looking for. Outside of sending the user to that registration form page, if there are other recommendations you have, we'd love to hear them. Most of the features in JFBConnect came from users at one point or another.
Thanks for all your feedback.. great to hear how user's are using things!
