I do think if someone does post something in the wrong area, or a duplicate thread it would be helpful if we provided the link to the correct forum. Far too often I've seen posts that do nothing but just say WRONG FORUM or DUP etc etc but that does not help anyone out. I'll be the first person to admit I'm guilty of that as well.
Mistakes happen, we are all human regardless of how many posts we have, or what our reputation level is.
