You can build and edit activities with your colleagues!
To add editors, find the dropdown menu in your activity and select Manage Editors. Add as many editors as you want, and get the whole department involved.
Editors have full editing power, including deleting the activity. Co-editors can only edit the activity, but not delete the activity.
Only one person can edit at a time. If you click Edit your activity while a Co-Editor is editing, you will see the message “Someone else is editing.” From there you can choose to either make yourself the Editor or go back to the activity page.
When you add an editor to an activity, they can find the activity under Custom Activities in the left side panel on teacher.desmos.com.
