Not working yet! This project is trying trying to make an easy version - I have a working system of over 750 blocks which uses players slots and each player has their own data, but it is too complex and messy. To put it metaphorically: In this project, one instructor tells everyone else to say they are here and counts how many people they hear. When that instructor leaves, someone else takes their job. In my complex system, everyone else says and hears on their own. Right now, you cannot tell WHO is online, but it would be easy to change that, and still use this compact system.
