I would be interested by the JFBConnect for my site.
1- I would like to know if this is compatible with the JomSocial (2.0.x) point system?
2- Is it possible to customize the language of the FB messages (registration, connect...), regarding the country of the user?
Thanks for your answers.
1) We work with JomSocial, but we don't natively assign any points for the user. When a user logs in through Facebook (using JFBConnect), they are treated like a normal Joomla user, so any actions that award points will work with a JFBConnect user.
2) Absolutely. We use different language files and configuration options throughout the component, and everything you see should be customizeable very easily to your language. All of the Social modules (Like, Fan, Comments) are automatically translated by Facebook to your Joomla language, so if you need specific language strings, there aren't a whole lot that you'd need to configure.
Hope that helps, but if you have more questions, let us know!
