To vote against an answer, simply post *Template:Oppose and sign with TheOneFootTallBrickWall (talk) 23:05, August 30, 2014 (UTC) under the it to symbolize your opposition. When voting against an answer it is recommended you post a short description of why. You can always change it at anytime, until the end date by using the Template:Unvote template.
If you would like to give a new option or even just make a little comment that is neither for nor against what you are commenting on, use the *Template:Neutral tag before it.
An example of unvoting in use would be *Template:Unvote. This shows up as  Support —.
Votes made by users not logged in (including regular anons) will not be counted.
Voting ends once four days pass and there have been no new votes (except during ties).
Unless five days pass and the vote is unanimous, then the vote ends.
If the available options to vote for are not what you want, go ahead and add another option and vote for it.
