The EnGage Portal is a place to upload and store drill files for use by the EnGage App. Using the EnGage Portal is the only way to download drill files into the EnGage Mobile App.
The Portal has many features that help with organizing your drill and allowing collaborators to access and upload drill as well. Consider the scenario where a Band Director outsources the drill writing to a professional Drill Writer. In this case the Band Director would be the owner of the account and the Drill Writer would be a Collaborator. The Collaborators are allowed to upload drill files into a Group owned by someone else so that they may be accessible by the owner, by other collaborators, and can be downloaded by EnGage Mobile App users using the Access Code.
