I need the start point for a WordPress procedure. I need a chart which shows in real time informations about the availability of a course. The participant has to see in real time if there are still places in the course he wants to attend. I would need, on admin side, a table to show me the status of the enrolments and course participants. (where this should be placed, actually where I can find it?) My last question is how to make a form for reprogramming or cancelling the participation on the course and how to connect this action with the table? For example someone makes a reservation to a course, and decide to cancel it, how I connect this action to the availability table?
