How do I add an apprentice before they're ready to be invited?

Under the Apprentices section, click on the orange + button in the top right hand corner.

A menu will pop up allowing you to enter the details for your new apprentice. 

When you scroll to the bottom, you'll see a toggle button that says Do Not Invite. Click the button and make sure it displays blue. You can now save and add your apprentice into the system, and invite them at a later date!

When you're ready to invite them, find their account. At the top, you'll see an orange box stating the apprentice has not joined yet. Click Send Reminder to invite your apprentice!
