Donator suggestion...

diamond donor- 5 months
gold donor- 3 months
iron donor - 1 month

They are going to add more perks, so making it last longer would be odd. Maybe diamond donor gets 2 months it's soon to be extra perks, but gold and iron stay at 1 month with gold's extra perks (only gold of course).

All server costs are monthly, so this scheme will not work here. However once the other servers come online you will get more perks and would be donating to "3 server" types (survival games, creative, and survival gameplay). More bang for the buck.
