Hi there. The very observant of you may have noticed that you can now 'Follow' another user. If you follow a user, you will see a message in your notification stream (the little star next to your user name at the top of the screen there) when the user posts a new scenario or starts a new discussion. It's also a way to show appreciation of the user's work. To follow another user, just go to their profile page and click the 'Follow user' button. (You may also like to look at your own profile - it has been redesigned to look much better now, and you can see whether maybe someone is following you...) Happy following.
