Integrate with Facebook Messenger for Invitations and messaging

Currently Geni allows for invitations only by email. The problem is you're never going to have the email of a relative you only just discovered. On the other hand, it's fairly easy to find them on Facebook by looking at their listed Facebook friends and comparing the names to their relatives on Geni. Further, while emails change, people don't change their Facebook profiles as often. It should be possible to provide the Facebook ID/URL instead of email for invitations.

Integrating with Facebook Messenger would therefore make it a lot easier to invite/contact newly discovered relatives, as well as stay in contact with those who may change their primary emails and no longer log in to Geni. It would be especially useful if eventually there could be some agreement with Facebook to bypass he "other messages" folder under certain conditions - perhaps if other relatives verify the relationship. And of course this could be a privacy setting within Facebook whereby one can either enable or disable family connections and/or the bypassing of the "other" inbox.
