For people who are seeing the "" icon, that signifies a thread that is very active and is almost like a "live chat". When so many people join a thread and begin replying quickly, the mod I've installed changes it to a "LiveTopic" (almost like a chat), which automatically shows new replies without requiring a refresh. When you reply to this thread, simply use this icon to reply and you'll see your post appear immediately. While you're viewing the thread, don't refresh it, there's no need. Just watch the last post. You'll see the replies appear automatically It changes the thread to a "Live" thread which as I said ends up working just like a chat.
