Social commenting is now available across the site in a number of locations. First KatsBits forum now support FaceBook comment posting, so long as you're logged in to FB it should be possible to post directly to a particular topic using a specific comment 'area'. Similarly a number of tutorials and other pages now include a Disqus comment feature. Please note that for full support it's best to post to the forums as both 'comment' platforms have limitations for the kind of technical discussion often necessary to solve problems. Additionally, note that usage of these features is guided by FaceBook and Disqus T&C respectively.
