Auto add users to "Registered" users based on group membership in FB?

No, we do not support this behavior as it is against Facebook's terms of service. Users need to accept your application and accept any permissions that you're requesting before JFBConnect can allow them to register.

No, the social stream module is currently fetched by your server and cached for whatever duration you set in the JFBConnect -> Configuration area.

We do it this way to allow your server to fetch the feed periodically without slowing down the page loads for all other requests. By caching it every 15 minutes or so, it means one page load will be a little slower while all other page loads will render very fast.

Unfortunately, since the Social Stream requires an authentication token and permission to fetch, it's not something we can load through Javascript without large delays or slowdowns to the page.

One suggestion you may want to look into is the Facebook -> Page Plugin, which can be configured using the SCSocialWidget module. You can see an example of the Page Plugin on the Facebook demo page:

I hope that helps,

No, the Page Plugin won't work for groups. There's no similar plugin from plugin that will show a group feed.

Unfortunately, no, we don't have a way verify a user is in a group and activate them automatically. I'm not sure what that would take to implement as it's not something we've had requested before, so I haven't investigated it before. I understand how it could ease some things, but I'm afraid I don't have any good suggestions on how to auto-verify them.

Thanks,
Alex
