Pretty self-explanatory. Between the three voting sites, tally up all the votes. For a maximum of 84 to 93 votes per month. From here, there are about an infinite amount of things you could do. Reward shop currency (expires or not), give a custom golden name and tag for one, two months, create fun rewards in the Hub, or just boring old in-game reward for the server of their choosing. Best way to reset each month? Reset at the first of each month at 00:00. There isn't any incentive for new players to vote besides vote keys per gamemode. But for whatever reason, a contest will always get someone interested. Not that I think voting does too much anymore now that Minecraft is out of it's prime (hopefully it gets another jumpstart), it is "something" that boosts the server up.
Thank you for creating this suggestion thread. This suggestion has been implemented. (See the Discord announcement, we will be starting rewards for each month's top ten voters, starting in October). Should you have any further suggestions, feel free to create another thread! Regards, The Staff
