Sure, you can vote for just one manga series. If you spot another manga, you can PM me or sickVisionz to update your votes.
I'm sorry for the wait. sickVisionz and I are currently working on the results while tackling some other projects, too. It will be up this month. Just need to run the numbers and are still waiting for users who haven't replied because they voted for something that didn't air in 2014.
Otherwise, I think sick and I will chop off their vote.
Thank you for your patience.
