Yeah I didn't even notice my user-title change :x.Having just changed title due to reaching 1,000 posts, I was surprised there was no Alert for it.
I think this would be a useful addition, assuming it's fairly easy to code.
Then I will 'unlike' post number 1, because it really is not that important for us. If it was simple & easy then it would be a different matter, but it is not.It's not actually that easy to do. Your title is determined on the fly, so we don't actually track when it's changed.
