We'll create fresh WordPress site with Booking Calendar Autofill installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin works with the Booking Calendar plugin and autofills fields, like “First Name,” “Last Name,” “Email” and “Phone Number” according to the user who’s currently logged in. Phone number isn’t included in WordPress by default, but is easily added using the “Custom Profile field as a Registration Field” plugin (search Google).
