WordPress for Windows Phone is an Open Source project, which means anybody can get involved and help evolve the project. Wikipedia explains it well:
“Open source describes practices in production and development that promote access to the end product’s source materials.” Wikipedia
The app is released under a GNU General Public License. Both the app and the source code are free for you to download and use in any way you want. Of course we’d greatly appreciate your help in making WordPress for Windows Phone even better, so if you know your way around the code, or if you just have some good suggestions for the app, you’re more than welcome to contribute to the project.
A good way to get started is to subscribe to and start posting on our development blog. This is where we plan the next big thing and keep each other updated with feature requests, bug reports, and fixes.
The source code is available via Subversion (SVN). You can browse the source or point your SVN client to the latest trunk at windowsphone.svn.wordpress.org, where you’ll find the latest development build. If you’ve never heard of SVN, you can learn more about Subversion on Wikipedia.
