I have an event with max 36 attendees. I had 3 on waitinglist. 1 user decided to remove himself from attendees list. After that all 3 on waitinglist got added. This is of course not optimla, when we have max 36 spots.
At the end of the day, computing and technology, like Joomla and JEM are here to help the end user and make our lives a little easier. Help us to be better.
