According to Google, this brand new forum was built from the ground up and offers a host of features. It will have a Q&A format to help users find answers quickly. It has improved search and integration with the Google Mobile Help Center. Google has added better spam detection and prevention. It will publicly recognize what it calls Top Contributors, and will assign more posting privileges to those who contribute help more often. Lastly, it will give user the option to subscribe to ask questions and receive answers via e-mail.
Google writes, "We've got a dynamic system of levels to reward your contributions, and a profile that you can personalize. You can subscribe to the forum (or to individual discussions) by RSS feed. You can even vote on which responses answer the question best and mark a best answer to a question you asked. As part of this transition, we'll archive the current Google Help Group, as well as the Google Mobile Community. We hope you'll use the Forum not just when you need help, but also to share your enthusiasm and give tips and tricks to the whole mobile community."
So if you've got some problems with Google's mobile services, you now have one more place to find the answers or information you seek.
