Hey, i got the idea from the facebook newsfeed, cause i really like that kind of feature. When i'm answering in a thread where Kier and some other (less important ) guys had posted and i'm writing an @ followed by the letter K, a list is popping up with all (or maybe just 3 ordered by count of answers in that thread) the users who has replied in that thread. The user who was mentioned get's an alert. Would be awesome if you could build in that feature. Greets from Germany Flo PS: I attached an example from Facebook!
