Fantastic post. I'm really glad you asked people to be courteous when responding to repeat threads. I swear some people do it just to up their post count. Others are just jerks. If a post annoys you, why do you want to invest the time into replying just to tell OP to SEARCH? Just ignore it. Better yet, be polite, and at the very least link them to this thread. Best, link them to this thread AND link to the redundant information.
Berating new members (or even older ones) about double posts creates an elitist mentality that is going to slow down the spread of information even more than redundant threads themselves.
