Facebook like in Kunena postings

Yes and no. JFBConnect doesn't have an option to automatically add the social sharing buttons to each Kunena topic. However, you can use JFBConnect to add these social buttons in a few different ways:
1) Use our JFBCSocialShare module
a) This module can be placed in a standard module position and will show the social sharing buttons in a standard fashion
b) Configure this module to 'float' the sharing buttons on the side or top of the screen. As the user scrolls through the page, the social sharing buttons will stay in the same place and always be visible.

2) Modify your Kunena template files and add the {JFBCLike} (and other social widget) tags wherever you want. This gives you more flexibility as you could add them wherever you want in the topic.

The one thing to be aware of with social sharing in Kunena (or any forum) is that all of the social sharing tools use a URL for the Like. So, when a user "Like's" something, they're Like'ing the whole page, not a specific post within that thread. Therefore, we don't recommend adding a Like (or other sharing features) in each post.. just once for the topic/page.

I hope that helps explain, but if you have any other questions, just let me know.

Thanks,
Alex
