If you're using a root domain (like "www.myschool.com") you might want to set up the naked domain (without the www), so that visitors who don't add the "www" will still be directed to your LearnWorlds online school. (Note: root, base, apex domains are all the same thing and can be used interchangeably when googling)
To do that, you'll need to set up the Forwarding feature in GoDaddy:
1) On GoDaddy, use the "Forwarding" feature to setup a forward from "myschool.com" to "www.myschool.com".
The "Forwarding" feature can be accessed in the "Settings" Menu click on "Manage"
2) On the "Forwarding And Masking" menu click on the "Add Forwarding" button
3) Type you LearnWorld Domain (including "www") at the "forward to" field
4) When you fill the form click on the "Add" button to complete the process. A new forwarding entry just inserted
You are done!
