- I have asked a question http://stackoverflow.com/questions/14171460/what-is-session-leader-in-ps-ax?noredirect=1 on Stackoverflow.
- I up-voted the good answer and accepted it.
- Later the question is moved to Super user as What is session leader in `ps ax` along with its up-votes and accept tick-mark.
- Now can I up-vote the same answer again?
Why is that? Didn't I just vote on it? Shouldn't it be prevented?
