You can allow direct registration in the Pathable app.
From the Dashboard:
- Go to Settings>People and Profiles
- Under Profile Editing, select "Allow new users to sign up for accounts within the app"
- You'll then select if you'd like to require an "access code" or not -- this access code would prevent anyone who did not have the code from being able to make a profile without your permission. You'd need to share this code with anyone you want to let in to your event, so it's not a good idea to make it public.
- Select the Message template email you want them to get when they register
