642 replies in a week?
That's a lot of people that need to get out more : )
Seriously, you could get 1642 a week, but quantity never makes up for quality, and this is a pretty serious forum.
Members won't usually waste their time confirming what other members have already contributed just to see their own typing, unless they feel they can add to the input.
That's a good thing, you get the advice without trolling through page after page of the same advice, and with 642 replies, there has to be a LOT of repeat advice!
