The new UI of the Community forums looks nice and refreshing. Great job!

One suggestion I do have is to make it easier for users navigating through many posts to not lose their place. When scrolling through topics and then after reading a specific thread, when browser Back button is used. It always navigates back to the top of the forum list. It would be nice if it brought the user back to the position in the list to the topic where they came from. 

Note: This is my experience when viewing the Community forums on iPhone Safari.
