Looking at the number of votes [this question][1] has received, I would like to ask everyone interested to cast their vote whether they are happy with the current time cutoff for changing votes on questions/answers/comments in the first few comments to this question. Warning, you can change your mind only for less than a minute! Also, feel free to share your reason/opinion in answers/comments.
