Facebook & Events + & Meetup.com

We have Events +, also a Facebook page that is private and a Meetup.com account.

What would be the best way to make them all work with one post? From looking it over, posting to meetup, then it sending to the website with Events + and then that sending to Facebook seems it would work?

Is it possible to have the website send to meetup.com? That way it is sending out to others from the one resource?

What would be recommended so that we get maps, and all other information on all web resources?
