I think it would be useful to indicate in some way whether or not there has been a post since the last time a user has opened a thread in the forums, without them having to actually open up the thread. This would make searching for posts to read much easier. The same feature would be especially useful for groups, so we wouldn't have to keep clicking on each group to see if there has been any recent activity. This could be done by changing the color of the title of the thread/group when a post has been made since the last time it was opened by that user, or by putting an indicator to that effect in words somehow (like, at the very least, adding some text to the list of groups the user is a member of that says when the last post was made). FS had a feature like this (different colors for threads that had a new post since they were last looked at, or something to that effect... can't remember exactly what it looked like right now), and I found it to be invaluable. Does my rambling description make any sense?
