We have a third winner and number four is very close. The last one has gotten far, but will take a minor miracle to get through with only two days to go. Unless ... voters use more votes. Remember that you have FIVE votes. On average, voters have used just slightly over two votes.
If you want to change your votes, just delete them and you can start over. There still is time, but it is fast running out now.
Also important to note: this is not a popularity contest. Participants can win electronic medals, but not a first place. The question is just if this group thinks that the articles nominated are worthy of the medal.
