Review the Invitation
If you selected yourself as the Recipient, you should receive an invitation in your Inbox. Let's look at it.

9. Try It: Review the Invitation to Share
Go to Mail->Inbox.
Select a message: I'd like to share my calendar....

What Do You See? On the right side in the Reading Pane is a link to Add This Calendar.

When a Recipient adds the Calendar, the linked Calendar will be available in the Calendar list. The link is live: any updates made to the linked Calendar will be displayed immediately.

Keep going...

The Computer Mama Sez: Please do not click on Add This Calendar. We just sent the invitation to ourselves, so we already have the Calendar called Charlotte's Website, OK?
