Can I share an invitation on Facebook, Twitter or other social network?
If an invitation is set to “open”, then the event creator and all invited guests are able to post to Facebook, share on Twitter, or select any other popular social network to submit the invitation to. Simply go to the invitation, and look for the “Share Invitation” box on the right hand side. There are buttons to share on Twitter, Facebook, or click the “Other” button to select from a larger list.
