Google analytics is software that allows us to produce anonymised aggregated reports of site activity over specified periods of time. This way we can monitor traffic to and from the site, and monitor the growth of our community
Note that the report seems to look best in Explorer rather than other browsers - Opera etc.
The reports are very comprehensive and you will be able to look at a wide range of information.
