I have noticed that quite often we get questions along the line of "I am creating my world, I have come up with a map, does it make sense?"
You can find a list here
These questions do rarely get closed, however I find that they often revolve around some basic concepts which could be better handled in a wiki sort of answer.
Therefore this call for action: if you have the time do so, would you start this wiki where we could collectively "dump" our knowledge time after time?
I have started the wiki here, feel free to chip in
