I disagree, or maybe you didn't understand what I'm asking for.
At some point, someone needs to click on the rewards to go to the next map (or the endless well).
Most often, we wait for players to have contributed before doing so.
Before the current structure, we actually wrote down somewhere who already participated.... we usually didn't care that much for everyone to have participated before closing the first map, because the rewards are... not that great, but we usually waited for every active player, including guys who said they would make an effort to connect, before closing the second map, and the third.
The information Innogames gives us is not quite what helps us make the decision, unless they changed the reward system.
I still need a list of *everyone* who contributed to *either the first or the second map* in order to decide to close the 2nd map.
So...I still need to write things down, most specifically, the list of contributors to the first map... and I need to check that everyone is either on that list or the list of the second map before closing the second map.
