In a Google Groups thread, AdWordsPro.Sarah tells us that there will be a new forum opening on November 5th .
The new forums will boast user posting incentives, integration with the help center, enhanced user profiles (personalization with social -- photos too!), rich text posting, and video capability.
Meanwhile, the Google AdSense team reports that they, too, have started a new forum, and it's already available. Here's the link and here's an interactive feedback forum that complements it, where you can report bugs with the specific forums.
Google Chrome is also changing its home, according to another Google Groups post. There's no date on this launch, but with the AdSense forum debut, it looks promising for all Google Help properties.
