If you're going to correct people on their spelling and grammatical errors then you shouldn't have any errors in your post.  Why is that? why does what they says becomes invalid only because they made a mistake? I mean, don't get me wrong, I can't care less about OP's correction. We are from every part of the world, so lose/loose can be not that obvious to non native speakers. Therefore, fuck OP's post... but this does not mean that only because they want to notify common grammar mistakes that the post should be spotless
