Facebook sent emails saying, “We’re trying out a new feature to reduce the amount of email you receive from Facebook. Starting today, we are turning off most individual email notifications and instead, we’ll send you a summary only if there are popular stories you may have missed. You can turn individual emails back on and restore all your original settings at any time.”
At least they let me know about this change. It’s a good reminder that you might want to once again check your settings and make sure they’re what you really want.
I changed my settings back so now I know when you post about me. Just warning you!
