Before you create any classes on the site, you will likely want to add an email restriction so that you only get students from your institution.  If your school gives out email addresses @yourschool.com you can configure DragonTeach to only allow signups using those emails.   

1. Enter your admin area on your instructor site
2. Click on the DragonTeach menu item
3. Click on Settings
4. Put a check in the “Require” box beside the setting for “Limit users by Email”
5. Add as many domains to the list as you would like
6. Save your settings
