Re: Players controlling time.
Shinyclef thought of a voting system similar to what Ryder mentioned, where a player types a command, /voteday or something, to put out a vote to make it day, without broadcasting anything in the public chat to avoid as much spam as possible. And so the player might say "Hey lets make it day please" and those who want it to become day can use /voteday, and with enough votes it will become day. But if more people vote to keep it night, or if not enough people vote for day, to hunt monsters or etc., it will stay night.
Not a bad idea in my opinion.
