If you are really interested in the text, use the inspector, navigate to the #content div and then you can toggle the text-shadow on and off. I hope this helped!
So what's the use case for this? You basically have to make new profiles for this, right, so you don't risk your emails accidentally popping up when FB makes a slight adjustment to their API and default privacy controls?
Also, theoretically, you cc everyone you want to see an email...so FB notifying does what exactly?
