I won't disagree. Yeah we've all seen the same topics 10 million times, but its the nature of the beast when it comes to forums. Personally I don't think this means that we should say "go search dumbass" in not so many words to these guys though. It kind of puts off a negative impression to those that are new, and doesn't leave
with too good an image really. Instead, I'd think it better to lightly touch on the question, maybe post a few links, and then mention that searching the forum here should return some good results for information.
I'm not trying to be a jerk or anything, but saying "go to google and search" seems to have a couple negative effects. Kinda says, "hey we're not willing to help you so do it yourself, and its also made the suggestion that they should leave this website and go to a different one, in this case, google.
Just my simple $.02 but hell maybe it's not worth anything.
