So... I have an idea for a feature that requires Facebook integration. I suspect it would be a very viable commercial extension all by itself. I'd say it's 80% Facebook integration and 20% front end. Theoretically, the Facebook integration would be simple presuming that the site is already properly configured with JFBConnect.
I'm considering doing this myself, but since it would leverage your API (and require your product as a base), I'm thinking I'll pitch it to you and see if you'd like to collaborate.
Want to drop me an email so we can chat?
PS: Using the forum for this because I don't see a place on the site for such a query
