JFBConnect has a 30-day money back guarantee, which is the only method we have to let you try JFBConnect. If you want to test it out on your site, you'll need to subscribe. However, if you run into any issues, we have excellent support and if you still can't get things going, you can always get a refund.
As for the features, what you're looking for is definitely one of our core functionalities. JomSocial even has specific integration just for JFBConnect to improve the social network integration options over their basic integration.
I hope that helps, but if you have any other questions, just let us know.
Thanks,
Alex
