Invite on facebook

Is it possible to send invites to specific people with the facebook plugin? How can I do it?

I know I can post on the user's wall, but I'm looking for that pop-up with the list of their own contacts to invite directly.

Thanks in advance

I would also like to know if this is possible, thanks...

You would need to handle that outside of construct2 I believe. I've personally started using php to interact with Facebook. You can access all the features including Facebook credits. Here's a link to help you get started if you want to branch out to php.
