Leslie, I believe I reset mine on one of the emails. Seems like it is one of those boxes you check, or uncheck.
I just edited my post to say I found a little box hidden at the bottom left of the screen where you type stuff to "submit". It seems to be permanently set to "Get notified when others reply" but there is a drop down menu to specify how to get notified. Mine is set to "Site Only (no email)," and yet I still get e-mail. And it appears I have to uncheck the box each time before hitting the "submit" button.
