If you would like to be told when there's a new entry in this blog, you can "subscribe." Whenever there is a new entry you will receive an email, an RSS feed.
To do this, scroll to the bottom of this page and where it says "Subscribe to Posts (Atom)," click on Posts (Atom).
This will open a new window. Go down to the bottom right and click on Subscribe in Mail.
That was easy, even if not obvious...
