There may be rare occasions when you want to delete all of the classes in a session. Obviously you should be careful doing this because if you delete classes in a session, the registrations for the class may be unrecoverable.
To delete all the classes in a session select "Calendars & Events", "Session Related Functions", "Delete all Classes in a Session"
This feature is handy if you've copied a set of classes to a future session using the "Copy all Classes in Session" function and you need to delete the copied classes and start over for some reason. You will be asked to confirm that you want to delete the selected classes.
