Features question: user list by number of messages posted

[edr]

This is a question about Vbulletin features:

Is it possible to display the number of users by number of messages posted. I tried the demo admin panel at Vbulletin.com, and "top posters" was a feature of "find users", but when I tried using it, I only saw the admin profile. What I'm interested in knowing is if the admin can generate a listing of users by number of messages posted overall, and/or over the last 24 hours. I just want to know if this is possible.

Thanks for your help.
