I'm actually looking to do something similar. I'm looking to find some analytics in order to assess who my top performing members month by month are in the overall space. Just something where I can give them a little bit of recognition for their work. Like a "Top Ten Users for July," and then August, Septemer, etc.
DId you make any progress on getting your numbers? If so, I think it might be helpful for me.
Let me know.
(BTW, I use Business Objects for my analytics and don't have access to the SQL editor in the system, for whatever reason.)
