Hi,
I´m about to try piwik out on an intranet, it´s done simple so that any visitor can get anonymous access by appending /statistics/ to the URL.
Our intranet is messy, and I´m trying to pick 3 basic things I can teach people unexperienced with web analysis, but talented in written communication that is sure to improve the effectiveness of their part of our intranet. (The overlay won´t work due to some proxy/firewall reason).
