Email problems

I never get any notices of replies to my posts, even though I have it checked in my control panel settings. I’ve been told by others that they can’t send me emails from this site. Whenever I check my email address in my profile it is changed to my user name. I’ve changed it back to my email address several times but it keeps putting my user name in the box when I check it the next day. Anybody have a clue as how to fix this problem?

It has never worked for me either. It is nothing you are doing wrong.

I used to get notes of a reply to my postings in my email, but no longer. I wonder what went wrong? It has not worked for about a month now.
