I had once deactivated Add Link to Facebook plug-in because it seemed to interfere with people downloading my main blog page. I tried another Facebook link, but finally came back to this one. I sure am glad I did. A couple of simple early problems setting it up were promptly solved by Marcel and now it works fine. Posts go to Facebook with the right thumbnail(my logo). Thanks Marcel. Being available to your clientele for problem-solving is the right strategy. I'm sending you a donation.
