I have activated an "email notification" feature which sends you a daily update on new posts on this blog. See the "Info" section at the top of the side bar. [I use Google Reader to keep up with the blogs I follow, so I never felt the need for an e-mail alert system until a friend asked me for it.]
If you wish to subscribe via e-mail, follow these three steps:
Enter your e-mail address in the text box.
This opens a new browser window / tab, where you verify you are a human.
An e-mail is now sent to the address you just provided; click on the link in that e-mail. That's it.
The e-mails themselves will be sent by FeedBurner (see the FAQs), a service that I have been using for several years for "burning" this blog's RSS feed.
