On Wednesday December 21th, our Postini Forum will be migrating to the new Google Groups infrastructure shared by other Google Product Forums here:
By browsing through those groups, you can see what you'll be getting in the new platform including the refreshed look for Google products and improved categorization and voting. You can continue to use the forum as normal. As the migration takes place, you may be directed to our new interface. No action is required on your part and all account information will remain the same.
Please continue to use the forums as normal and post here for thoughts and questions about our new forum platform.
