You can share your Ripl animations directly to any Facebook Groups that your personal Facebook account is the admin of. Because of the way Facebook permissions work they won't allow us to share your creations to Facebook Groups that you're a member of but not the admin.
On the final "Caption Your Post" screen, tap the plus button ("+") next to "share to:" displayed above the keyboard. This will show a list of social media network options. If you already connected your Facebook Group in the Ripl Menu under "Account Settings" any Facebook Groups that your personal Facebook account is the admin of will show up in the "share to" list.
If you haven't connected your Facebook Groups yet, tap the settings icon in the upper left corner and then tap "connect" next to Facebook Groups. Tap "done" to return to the "Select Accounts" screen and tap to select the Facebook Group(s) as an output for the Ripl animation.
Tap "done" to exit the "select accounts" screen. Don't forget to press the final "share" button in the upper right hand corner to begin uploading your animation to your selected social media networks.
