I changed the menu at the top of the website page. You’ll see it talks about “Join the Mailing List” and “Join the Email Alerts List”.
The Mailing List is for a weekly email that provides a summary of the posts for the week as well as other news.
The Email Alerts List is an email once a day (but at most twice a day), with a summary of new posts on the site.
So if you want to keep abreast of changes as and when they happen, then this is the best way to keep up with things that happen on the website!
