The Play! Framework 2's ecosystem is evolving fast and well; a good metric is the ever-increasing number of questions related to it on Stack Overflow (nearly 2000). Its information page at http://stackoverflow.com/tags/playframework-2.0/info is a great place to search for advanced information.

Another way to get help from the community is to use the Google group at http://groups.google.com/group/play-framework, where hundreds of topics are discussed by developers, including Play! 2's committers.

There are already a lot of applications built upon Play! Framework 2, so the number of use cases is increasing day by day. As a consequence of that, the number of plugins available for Play! 2 is also increasing very fast. At the time of writing, there are a lot of third-party tools, services, and libraries that can be easily integrated with it.

Typesafe, by willing to have them gathered at a single place, has reserved a temporary place for them all at https://github.com/playframework/Play20/wiki/Modules.

But there is another project that has started to ease the integration of new plugins; it enables developers to create their own plugins and publish them, with some constraints on the quality, using a rating system. This project is open source and is running well; it can be found at https://github.com/play-modules/modules.playframework.org.

As part of the ecosystem, we will find a lot of blogs that mostly contain information on Play! Framework 2's tricks and hints. A few of them are listed here:

Obviously, you can also search for your local meet-up (or similar) group about Play!—there is always one, and that's probably the best way to be a part of the community.
