Using both Facebook and LinkedIn

Cheree,
When using the SCLogin module, there's a "Show Connect Account Button(s)" setting. When enabled, if the user is logged into Joomla with an account that hasn't connected to Facebook or LinkedIn, there will be a "Connect accounts?" link for each network that hasn't been connected yet. If they click those buttons and login, it will connect their account so they can login with that social network later on.

JFBConnect also has a "Automatically Link Facebook Users by Email:" setting. When enabled, if the user tries to login with Facebook and their FB email address is already associated with a Joomla user, they will automatically be linked together. That setting will be coming to JLinked in the next release.

I hope that helps explain, but if you have any questions, just let me know.

Thanks,
Alex
