I found the following under Your Stuff/Notifications; which implies I will be notified, but it doesn't explicitly state that, or when any possible ications will be made.
Below is a list of items you are watching. You can use the drop down below to filter by type of content, forums, or users.
That all depends on what options you have selected for your account
I receive NO email notices, because I have my account set to NOT receive notices
You must set YOUR account to receive notices
Dear Mr. Smith:
Thank you for your interest in responding. However:
1. I checked the first link you suggested which is how to unsubscribe. it showed me a list of things I posted, so supposedly I'm subscribed to them, but I'm not getting the notifications by email.
2. In contrast to the tutorial on your first and second link, there is no path Your Stuff/Profile. Your Stuff and Profile appear to be on the same level of sub-headers.
