Org admins have the ability to add a company message that displays to all users. Should you like, you can add a link to this message as well. 


Here is an example of a company message with a link:

Your message is: "To learn more about Autodesk click Here."  To add a link to the word "Here" you would edit the text as such in the message box:

To learn more about Autodesk click <a href="">Here</a>.

The <a> is where the link starts and the </a> is where the link ends. The text in the quotations will not be visible.
