Now that I’ve moved the blog to a private hosting company, you can register to become a subscriber to the blog using the links on the right. This offers a bit more than the email subscription that has been available for a while. Becoming a subscriber means you can create a profile with some information about yourself, which will be available to people who read your comments (if you are logged in). It also gives you some (not many) controls over forum notifications. I may add more features as I discover them.
I will keep the current email notification feature for those who prefer to keep using that.
