Is there a feature in Stack Exchange that will allow me to receive an email notification when someone comments on my question or answer, or answers my question?
The email notifications option has been moved, from the multicollider to your profile. In order to reach it:
- Go to your profile by clicking on your username at the top of the page.
- Choose Preferences. You'll find it near your About me.
Check the blog post "Improved Global email notifications" by Jeff for more info.
