IMPORTANT: NO LONGER MAINTAINED.
We DO NOT actively maintain this extension anymore. The rate at which social networks implement breaking changes we cannot address (bar with a massive rewrite every 3 months or so) make it a bad business idea relying on social networks for account creation and logging into your site. As a result we decided to not implement these features on our sites which means that we have no use case for SocialLogin anymore. As a result we have no reason to maintain it.
