There are two ways to set up your layout so that comment notifications will be emailed to you.
1. When you are uploading your page, scroll down to "Extra Options."
Select "Yes" from the drop-down menu next to the question, "Want to be notified by email when users post replies?"
2. After your layout is posted, you can click on it to see the Photo Details. Click the "Receive email updates" icon which looks like an envelope. This enables this feature.
