Blogger has informed me of the following:
Recently, the Feedburner team released a system update announcement, that the email subscription service will be discontinued in July 2021.
After July 2021, your feed will still continue to work, but the automated emails to your subscribers will no longer be supported.
If you do follow my blog via e-mail, you will need to find another way of getting notified of my blog posts. My blog's Facebook page can be found HERE. If you have an RSS reader, there is a widget on the right side of the page... assuming it still functions.
