Yup, formerly when viewing a thread's contents, as you are now, each author who had posted to that thread would see a [Delete Message] button on the line following his name, date and time. With that gone you now have to go outside the individual thread, bacdk to the full list of threads, to get a 'Delete' option. Not the end of the world, but having it right there was kinda handy. When correcting typos, it was faster & I suspect helped in avoiding crossposts or out-of-order messages in a fast moving thread.
