This module helps you to make appointments. It needs some explanation...
First you set the time zones, called time slot, for one day. Then you add the capacity for this time zone. How many appointments you want in this time slot.
Eg. you are a doctor who wants 4 patients in one hour. Here i set the capacity to 1. I only want one appointment in that hour.
You can add fields in the content type. I added a textfield for some explanation concerning the appointment. From the moment there are as many appointments as the capacity indicates, the slot becomes not available.
There is a view to show you the status. You can make your own views to see the appointments.
