In one of my old servers they did ranking by time played, so 12 hours would be member rank, 48 hours next rank, 7 days next, 14 days, 30days .... etc... all play time AFK time didn't count and player could see how many hours they had played and what the next rank up / time would be. Just another Idea aside from voting. This would mean that players would spend more time on the server to rank up, usually contributing more than just votes to the server.
