Individual classes can be set to not allow registration using the "Registration Type" setting for the class, but there is no easy way to change this for all classes in a session.
Here is the best work-around to show all classes without actually allowing registration or pre-registration.
- Create your new session and set it for "No Pre-Registration"
- In the Session description, put some bold or "H2" format text to explain your pre-registration and normal registration dates
- Activate the session
- Select all your classes (using the widget at the top left of the classes list) and put them in Pre-Registration
The session schedule will now appear on your site, but no registration will be possible.
Limitations: If a family ignores your description of registration dates and clicks the pre-register link, they will see a message that says the class is in pre-registration but gives "--" as the date registration starts.
