What should I do if a Document I want to edit has been checked-out?

If you want to edit a Document but have found that it has already been checked-out:
Either:
1. Wait for the Document to be checked-in. You can VIEW the Document without making changes to it by clicking on its Label.
OR
2. Send a Message to the Person who has checked it out. Their name will appear in blue, beside “checked out by” (in bright pink):
2a. Click on their name to open the person foldout. 
2b. At the top of the foldout (in blue), click “Message” to open the “New Message” foldout.
2c. In the New Message Foldout, select from “People I work with”, “People in one of my Groups”, or “People on one of my Projects”. This will limit your search results in the next field, making the correct recipient easier to find.
2d. As you type a person’s name, full names will appear in the dropdown. Be sure to click on the correct name to add it to the “to” field. Click “x” to remove them. 
2e. Type your Message’s Subject in the field provided.
2f. Type your Message in the field provided.2g. Click “send” at the bottom of the foldout to send your message.
