Hi,
This is a report I created that allows you to see all the reports that were run for a given time range. You can then see for each report the requests made, and the parameters used for the request. Below is a screen shot. I have submitted it to footprints but I thought it would be useful in here as well.

I have removed the attachment for this item since it is now in footprints. Any updates that I make to this project will get posted there. It is filed under Solution #305 Report Request Viewer (Shared Reports - Browser) .
