I might be wrong but...

I might be wrong but I think there is a bug in the second voting system of the voting - tutorial hosted on this site, it seems to me that the same player can vote multiple times. The fix would simply be to disable the trigger once it's been called just like in the first voting system.

I myself have implemented a different voting system in a Maze Defense map currently played a lot on Northrend (not sure about others) which allows you to kick players. If you want to see how it works download it here . There might be some small redundancy in it as it was the first trigger I've ever made but I haven't had any bugreports. (Maybe that's because nobody knows how to contact me).
