I post to the site regularly (at least every fortnight) and there are two ways to receive updates:
The easiest is to subscribe to receive an email with each new post.
The other way is via RSS. Click on the feed button in the bottom left of the site. This uses an old web system called rss. There are lots of feed readers but I use feedly.com and it’s available on your phone, tablet or wherever. Here’s a blog post about how to setup Feedly to receive updates via RSS: skellis.net/blog/how-to-receive-updates
