In this forum you can ask questions about the Piwik Platform such as:

Piwik is a powerful Web Analytics tool which tracks and reports your users’ data, but it can be used to do much more! With Plugins you can build custom reports, integration and track new custom data, create a new visualization, integration with other services and platforms, and much more.
Plugins can be easily published on the Plugins Marketplace[/url], and themes on the [url=http://themes.piwik.org]Themes Marketplace.
There will be more Dev doc coming soon, but we look forward to talking to helping you build great plugins and themes for Piwik 2.0!
