Add votes to statistic in users report

Hi!

I'm trying to create the report with most active users in system who contributed voting for the features.

- It looks a bit strange for me (I'm a newbie using your system so far) that i cannot create reports for users in Reports section but for some reason user reports are located in manage - users menu

- when I create new "user report" I can add "Statistic" field. Once created the column shows two numbers without any clarification what are these numbers. Please add description somehow or divide those numbers into separate columns and name them accordingly.

- I do not find ability to add votes column here. It looks like "statistic" shows comments and topics created, but doesn't have votes in there. Would you be so kind and add Votes column or at least add it to "statistic" column as a separate number?

Thank you in advance!
