I feel like a common usage of Forms would be to gather information from other employees.
I believe it would be great if a form could only be filled in by someone in your organization (logged into Asana), and it would populate the subsequent created task with that user’s name/email address (perhaps be able to tag them as the task creator). In that way you minimize the information they need to enter, you avoid externalizing a form, and you can create processes around internal users creating tasks, requesting things, etc.
