The emails that notify us about new posts in a given thread suddenly stopped working correctly this morning. Their subject line used to match that of the thread; now they mention the poster's username. (This means that GMail, et. al., can no longer organize all of the emails for a given thread into a single conversation.) The full content of the new post used to be in the email, and has now been replaced by a tiny excerpt. (Thus, I can't immediately see if a given post is something that I'd already read previously when I was on that thread.)
Please revert this functionality back to where it was before. This new behavior is highly annoying, and is pushing me to simply auto-send the entire lot to some little-used folder.
