0Vyger 6 years ago I hate to disagree with kelseymh but yes you can vote for your own instructable, but only once. One vote will not get you to far in the rankings so it really doesn't make much of a difference. Of course the logical thing to do would be to vote for only yourself and no one else. But then if everyone did that then everyone would only have one vote. In that respect the authors cancel each other out. Which is why its up to all the people viewing the contest entries to vote for what they find is deserving. And also why you should vote for other projects that are good. However, in the end votes do not determine the winners. They help to narrow down the field but an outstanding entry that comes in at the last minute and so will not get that many votes can still win based on the merit of the project.
