15 votes seems like a small turnout considering how many members are on the forum. Maybe adding a week will get votes from a more sizeable portion of active members.
To be honest, I don't consider it a small turnout. I'd maybe agree if only 5 people had voted, but we technically have more than 6000 members - I certainly don't expect all of them to vote XD. In terms of members who actively post, I'd consider 15 to be an OK amount. More would be great, absolutely. A few people have voted since I posted that, and I expect we'll get a few more before Saturday.
What's worth remembering aswell is that we would probably have more votes if it was just a straight-up poll, because that requires almost zero effort. The nice thing about this system is that the people who have voted have taken the time to think about it.
REMEMBER TO GET YOUR VOTES IN EVERYONE, ONE DAY LEFT!
