I think there should be a donation perk that allows people to use their additional homes without having to vote first every 24 hours or so.
The player would have to donate about $30-$40 to do this (depending on what's agreed if this suggestion is accepted), making it the highest donation option. But when somebody does donate for it, they will be able to warp to their additional /homes without having to vote.
Even though this would mean that people won't be voting I think this will benefit the server due to these reasons:
1.) Let's face it, most people don't fill out the captcha on the voting sites, and /homes are probably the main reasons people vote, so this will give people an incentive to donate without having to go on the site to "vote".
2.) This will be another way people can donate to the server to keep it running. And since a lot of people don't actually vote, them donating for the ability to not have to "vote" to use their /homes will actually help the server possibly more than if they actually voted (As I'm sure there's more people who would want the ability to go to their /homes without having to vote every so often, and, as said before, most don't actually vote anyway).
