I recently asked a question, which has received both comments and an answer. I was expecting to get an email indicating that there was a response, but have not seen one. I also did not find a place in my profile to indicate if I wanted to receive such an email.

Should I have received such an email? Is there a way to turn email notification on and off?

My email account is with gmail, in case it is known that their spam filters block email from this site.
