Sunny,
Right now, we don't have an auto-posting feature to push content to the different social networks.
With JFBConnect, you can create different social channels which content from your site can be posted to. The way it works now is that an admin must navigate to the page to share and push the content on their own. They can add their own comment about the page and select any of the channels you've created and have it pushed to them all at one time. However, it's not something that happens automatically when new content is created.
We're planning an auto-post feature for later this year to do what you're looking for.
With that said, if you already have a custom component, the code required to push to channels in JFBConnect is actually pretty simple. We could gladly provide you a code snippet that you could implement in your own component to push to any channels you've configured. It would take a little bit of code modification and testing on your part, but wouldn't be overly difficult if you already have a custom component developed.
I hope that helps explain,
Alex
