How to get a field to show a default value

Hi kyle,
I would like to create the field cb_notif_post BUT it needs to be ticked automatically unless the user decides to untick it. I have created the field but cannot set the default value of it somehow.
How can I do it so that it for all the 10.000 registered users I have already on my website, it shows a 1 (as in that they have subscribed to the notifications)?

Currently you can only set a default for registration so the field would have to be displayed on registration. Your alternative is to use CB Auto Actions and a Field action acting on the after user registration trigger and setting the field to 1. That'd make it checked for new registrations. For existing users I'd just do a quick database query with phpmyadmin and update the field to 1 for everyone.
