Requiring that parents enter an email address
When a parent logs in to the system to make a booking they are asked to enter an email address. This email address is not used for authenticating parents, and entering it is optional, but you can make it mandatory by ticking the relevant box under Required Login Fields under System Settings > Login Settings.
Any email address that a parent supplies will be added to the parents record and used by the system to send confirmations of bookings, reminders etc.
By default it is not enabled, meaning that parents can log in without entering anything in the email address box. If you want to make an email address mandatory, go to Settings > Login Settings then tick the box and click Save.
On the same page you can also change the text parents see when they go to log in.
