API sample report to run for individual site dialogs

You can run a report from the site page that would include the individual's name, department, dates of individual dialogs from a time period set at the top of the report (like the activity report) basically, it would be an activity report for the individual dialogs. Can't do that now through the site page because there is so much other stuff in there plus user should be able to export to Excel so they can sort it if they want to.
