There is a “Sign me up!” button in the right hand column from which you may subscribe to receive an email notice of every post. If you want to later Unsubscribe, this option is at the bottom of the email notice you get.
Additionally, The Comment created a Constant Contact e-mail list to notify you of important postings. This list was created from previous subscribers, but I recognize that some people may have moved or are no longer interested. Constant Contact has an Unsubscribe feature that will automatically remove you from that list. You can also email cityhamilton (at) gmail.com to subscribe or unsubscribe, though this might be a bit slower.
I won’t abuse the e-blast, and plan to use this method only occasionally, so be sure to check back to this site regularly.
