Go to your Dashboard
Go to "Edit Profile"
See "Share My Profile"? - check that box
Now under "Show My Email Address" - check that box
Now when you leave a comment, when someone clicks on your name they will be able to find your email address. If you really don't want your email to appear with your profile, please at least leave your email address with your comment.
I have now deleted 6 comments and there will be more as I go back through. If you are a "no reply" person, please comment again and I will gladly add you back to the list!
