From 'My Assignments', find the assignment you would like to share and click on the 'arrow' icon.
2. Use the 'Link' option to copy the preview link to share with your colleague in any channel you normally use to share.
3. Next, you can share the copied link by clicking on the 'Social' link. You have the choice to share using Facebook, Twitter, or email.
4. The recipient will click 'Copy to My Assignments' and they can use the assignment "as is" or continue to customize it.
Note: If you are using an LMS like Canvas or Schoology, it's easier to create, customize and share assignments in Writable first, THEN return to your LMS and create a Canvas or Schoology assignment that links to what you just created in Writable.
