I'm looking forward to using the new features (pro-rating, etc.) from the new release this past week. Great job getting that out!

I wanted to suggest though that since a large value of these Public Discussions is the ability to find answers to questions without having to ask them again, and that since there are now a good number of irrelevant or incorrect answers (based on the product before these new pro-rating features, recommending hacky solutions, etc.), that you take some time to go through the old threads and add a brief comment anywhere it's appropriate along the lines of "This answer is no longer relevant as of our new pro-rating release Feb 2010, which allows you to xxxx.... See docs at xxxx...."

This would be a great help for existing customers to learn how the new system works without confusion as well as a way to ensure potential new customers don't seek another competing solution because it appears you don't support some of these very important new features you've just added.
