Just a number of questions. Google+ first, are you using the Moments API or a different method, and does auto posting from articles in K2 to facebook, twitter, linkedin and google+ accounts actually work. I got burned with Joocial regarding google+ feeds.
Does Social Backlinks post title, images and short text from K2 articles to these social media sites.
Can I set up a schedule for old posts to auto post at specific times?
