Forum Nokia covers development all of Nokia's major platforms: Series 40, Symbian and MeeGo (Maemo).
The 'design' section will cover both UI design and application process or concept. The 'develop' section will, going forward, concentrate on Nokia's three key developer frameworks: Qt, Web (WRT) and Java; other frameworks, including Symbian C++, continue to be fully supported. The 'distribute' section focusses on the revenue generation and distribution opportunities offered by the Ovi Store.

"We have worked hard to make the navigation faster and easier to follow; and you will see that we are grouping related information and tasks in ways that will help you to find precisely what you need, so that you can make the best use of your time.
And yet, even as our developer web site changes, some things will never change. We remain fully committed to open source frameworks, and building upon the strength of our global developer community."
