How do existing JomSocial users connect their FB accounts?

There's quite a few different ways that existing users can add a social network to their account:
* Enable "Automatically link users by email" in the JFBConnect -> Configuration settings. When set, if a user authenticates with a social network and their email address on that network matches the account of an existing Joomla user, the accounts will be automatically linked together.
* If a user logs in with their Joomla account, the SCLogin module can be configured to show "Connect Account" buttons, like you can see in the "My Account" menu above (which is from SCLogin).
* Create a new JFBConnect -> Account menu item where a user can manage the social network connections they've made.

Beyond that, you can add our 'Connect Account' links anywhere using our EasyTag, like {JFBCLogin show_reconnect=true}. If you add that to your JomSocial user area, or any other place, the social networks that the user *hasn't* connected with already will show to allow them to do so.

I hope that helps, but if you need anything else, just let us know.

They'd have to remove the permission for your application to post on their behalf. That's an option in Facebook.com in the Settings -> Apps area where a user can remove permissions that they've already granted.

When you say "it doesn't give me the option to re-connect again", do you mean that you weren't prompted for the posting permission again? You should be prompted to approve the posting permission again when you log in the next time with Facebook. Is this not happening after logging out of your site then logging in again via the Facebook login button? Did you make sure you logged out, then logged back in?

Hmm.. that's a good question. We do set the De-Authorize Callback URL when you run Autotune. That let's Facebook notify JFBConnect that a user has disabled the app.

Can you go to the Usermap area of JFBConnect and check if the "FB App Authorized" column has a red-X next to it for the user that you removed the app for? If so, then we should be able to help with some code that will fix our reconnect buttons. If not, we'll need to understand why the De-Authorize Callback isn't working.

Thanks,
