I am still not quite sure how it works. But it does seem to do the job on showing who the quality-posting folks are.
Me, neither, actually. By the time I'd done all my tweaks ("Let's throw another fudge in there to make avg daily posts more valuable if your peoplemarks are high", etc), I ended up with a rather nightmarish formula that does seem to at least work. So I hope I don't need to tweak it. Or explain it. <g>
I'm also curious to hear other thoughts on it. And in reality, it wouldn't be all that hard for it to return the top 100 or top 200. I'm also looking into making the score available either on profile screens (whether a person has made "the list" or not), or somewhere else where a person would see only their score and the elements that go into determining it.
If I can get SQL Server reinstalled here, I'm getting right on the message-text searching. It's the next item on my plate.
