HEY JUST PASSING ON SOME INFO. I THOUGH EVERYONE SHOULD READ THIS. or do you know everything and you don't need any more info.
Bad form. If you want to discuss something unrelated to the current post either create a new thread or find one applicable.
Thread jacking and mud-slinging are both unnecessary. There are other posts that discuss OC vs CC where you can chime in.
It's forum etiquette and it's not difficult.
