Suggestion #5

Give rewards to the top 3 voters of the server every month. Rewards can vary each month if you choose, for example: 1st-$100k, 2nd-$50k, 3rd-$30k. This could give players another reason to vote on the server. Also as time goes by and when buycraft is set up, you can change the prizes to: 1st-$50 voucher, 2nd-$20 voucher, 3rd-$5 voucher. This could keep the server interesting and bring more players to it.
