This is certainly a pleasant surprise. Thanks, JRiver, for your continuing responsive to your users' requests.
Just curious as to why I wasn't able to login under my old user name. Attempts to use "Shelly" returned an error message "no such user name". However, when I tried to reregister with "Shelly", the message received said that the user name was taken. I had to enter a new email address, as well, as reregistering with the previous email address, resulted in a another error message that the email address belonged to another user.
