Suggestions for helping low-pop servers

[Terminal Entropy]

I would love to see a message pop up on #4 (or whichever server has the most people on it) every once in awhile, that just says "Hey there's 3 other servers to play on, when you die you can switch over to those." It's getting ridiculous that #4 will have 60 people but #1-3 will be totally empty.
