Today I've voted for closing this question for missing any context and for the OP has shown no effort. Another 4 users thought the same (I suppose) and voted accordingly. (Furthermore, one of them left a comment explaining the OP what's wrong with his question and how to improve it.)
But our votes have been annihilated by Jyrki Lahtonen who reopened it without leaving a reason.
If I was wrong I'd like to know why, and eventually to apologize the OP for my closing vote.
Edit. Meanwhile the question has been edited by Jyrki Lahtonen, so I'm referring to the question as it was before.
