Want some of your favorite users to check out your story and vote or add suggestions? An invite button would be a good idea.
Invite users to stories
In addition to being able to invite other users to make casting suggestions on your page, I wish you could invite others to have special privileges on story. For example, being able to allow others to have administrative or management controls for a story, editing or some other kind of feature that would allow you to invite others to work on a story in a group without having to open up changes to everyone or have them only be limited to yourself.
