Hi Emilio,

Please find my answers from your inquiries below.

Facebook/Twitter/LinkedIn/GooglePlus/Instagram - Auto Post from EasySocial
Meaning - If they Post or Publish something in our EasySocial portal (http://www.LetsGoChurch.com), they want to auto-replicate this Post in all their social portals Facebook/Twitter/LinkedIn/GooglePlus/Instagram.

Unfortunately it is not possible to do so except with facebook where users can post their status update in easysocial and easysocial will automatically update it on their facebook account.

In order for you to do so you must create facebook apps and then submit the following item for approval, http://screencast.com/t/lDU3XO4j67 so that facebook will allow your apps to post a content from your site to facebook. After that during the registration using facebook login, user will see the options to allow them to post their easysocial stream into their facebook account.

Hope these help.
