TutorPanel uses several default templates for notifications for welcome emails, lesson reminders, lesson notes, etc.
If you want to customize any of these templates you can do this by going to the Account Management tab -> Notifications and clicking on the "Edit" button next to the template you want to modify.
Each template includes several variables that will vary depending on the recipient of the email or other factors. When you customize your templates be sure to include these in the proper format. You can view all of the variables by clicking "Information" in the sidebar on the right of the template page.
