Voting System within clans
I reckon a cool idea would be if a voting system could be implemented with clans like you create a vote for should we do wars daily then send it out set a time on it like 24 hours and people can click yes or no. This is just a basic idea of how it would work but i think its a good idea!
Do you mean a polling option
I think the idea for a polling system within a clan would be a great idea if that's what you mean. Something where someone can suggest an idea then the clan can vote on it. Your explanation where you use only one idea makes it sound more like you are just suggesting a system to vote on starting wars.
But a system for the clans to post ideas for changes to the clan and then vote on them is a great idea if that's what you mean.
