I would like to know why my answer was removed, as I believe it answered the question when no-one else had.
Your answer was entirely in support of another existing answer. It read:
No, you can't
As Colin mentioned, it's considered rude.
Subsequent answers need to add additional information to be retained. Because of this, your answer was removed. If you agree with an existing answer you can upvote it (once you have 15 reputation). Please don't add agreement with existing answers as a new answer.
