I know there is a Dev Tracker Tab at the top of the forums which is good to find important and useful information regarding the game. It would be nice if there could be an icon showing that a Turbine official commented in a thread on the thread's title in the listings. We have icons for sticky, attachments and subscriptions, it could go in the same area.
Since the expansion pack and subsequent updates there have been many problems and difficulties in the game. We get many posts on similar topics seeking a response from Turbine, this way it is easy to see when a response has been made in a thread. I have seen this on other game forums and it seems like it would work well here too.
I think it might make it easier for those browsing the forums to be alerted to important information.
