I think you guys are being a little too sensitive, no offense
Based on his profile, he's what, 12?
In real life nobody would have cared if an 12 year old didn't have perfect grammar or pronunciation or even if he pointed out the obvious. Why is it that just because it's online he now has to act any different?
And besides, he wasn't pointing out the obvious in that one post. He was just stating that it's no longer official "revision so and so," now it's actually v21. I didn't know that, and I'm pretty sure quite a bit of other people didn't either.
