Hi, Is there a plugin for K2 which allows user to login with already existing ID providers and let them comment and also share the content on the social networking sites. I want to use a single plugin for both. Have any one came across such a plugin till now?

I came across a plugin 'Social Login and Social share'( extensions.joomla.org/extensions/access-a-security/site-access/authentication-cloud-based/19293) which allow users log in Jomsocial sites with facebook, twitter, linkedin and many more ID providers. and also allows social sharing as well as social counter. It also captures important User details which is always useful. This is one of the best social media tool for Joomla I have came across. :) :) :)
