If you haven't checked it out already, then you should head over to our developer forum. It is one of the newer sections in the growth of the forums. And it's not just for developers!
The default Metro look on Windows Phone 7 is certainly beautiful, but is not for everyone. So if you're looking to change the look of your device, then go take a look through all the different themes that our users have created, you may be pleasantly surprised.
Next up, would you like to beta test some applications/games? You will not need an unlocked phone, and it's a good chance to try out new products before the rest of the world. Also, if you are a developer why not request some testers in the forum. It always helps getting a second pair of eyes on your work.
Then, for you more adventurous individuals, we have the Software Development and Hacking section where you can get help with a potential problem with Zune/Chevron or maybe just post screen captures of your WP7.
Finally, if you need help getting started with WP7 dev or want to take advantage of a great offer for free app translation to Swedish then go on over to the developer section.
