Sounds like you may be implying that posts from all the countless members who don't have a message count higher than 1500 yet aren't nearly as valuable...
Well, I personally think that the forums personality here is contributed to by a lot more members than the 6 to 12 old timers that don't seem to come around anymore with any real frequency. And, this is a community site... and, as with any community sometimes older people go and new ones come along. Not that long time members and participants aren't a good thing, they certainly are.... just that the new ones are just as important and sometimes replace ones lost. Such is the way of things in life.
MW should never be dependent on any one member, or even a small group of them, as far as I see it any ways.
