Example booking page
On a real member's profile, the Book online button opens their own booking system, where a patient picks a time and books it. We do not take the booking or hold the diary; the button simply sends the patient straight to the member.
Members add their booking link in their dashboard. Anyone without one keeps the enquiry form instead, and nothing on their profile changes.
