You can add contributors to your story by clicking on 'Share'. On the 'Invite' tab, you can add their names (if they already have an account on Sutori) or email addresses.

If you have set up tags (groups of students or classes) on your students page, you can also share with them.

You can add as many contributors as you wish!

Copying story
If someone has access to your story, they can copy it to have their own editable version. For teachers, this is an ideal feature for assignments as it enables you to pre-fill a story that students can then copy and complete.

Copying a story immediately opens up it up.
