I was getting some bad spam users registering on this blog so I disabled the ability to register. You don’t really get any benefit from registering so I’m saving people time and blocking spam. Anyone can leave a comment without registering. I moderate all the comments so I don’t let spam through that way. Also, anyone who wants updates by email can subscribe without registering so there’s no need for it.
If you find you can’t use the blog because of this change leave me a comment or email me at email@example.com.
