JFBConnect doesn't have specific integration for Ohanah, but I know they had (and I believe still have) integration with us. Their integration with JFBConnect is to use our Open Graph API to set the best tags for their Ohanah pages. That makes sure the title, description and image are better than what JFBConnect would set by default.
When they implemented the Open Graph integration in Ohanah, it was before we had Open Graph plugins, which make it even easier to set the tags in 3rd party extensions and provides a little more control over the tags themselves. However, their integration is just fine and, from what we've heard from multiple users, works as it should.
Of course, if you're running into any issues with the integration, or would like to see something else, let us or them know!
Thanks,
Alex
