I think that the server should offer a little bit of incentive for voting.
Dont get me wrong as a dedicated player I vote as much as I can remember, However from previous server experiences I have taken into conclusion that giving voting rewards do get more players and get more votes!.
Here is a few ideas:
Everytime you can vote, let the players choose between a couple of options such as:
1. 10m
2. Barrows Piece ( Just an example, not really practical
3. 5k ea Rune
4. Abby whip ( Vote a couple times )

So give me some feedback please
