We use Feedburner’s (normally) excellent service for allowing blog readers to subscribe to this blog and be automatically notified via e-mail when a new article or piece of content has been posted.
We’ve heard from some readers that the Keep Informed! link on the site sometimes doesn’t work. In almost all cases this seems to be caused by some sort of restriction that organization’s IT people have put on their network firewall.
If you’re having problems, we’d suggest typing in (or clicking this link) the web address http://www.feedburner.com/fb/a/emailverifySubmit?feedId=2515755&loc=en_US into your web browser, follow the simple instructions (you’ll be asked to enter your e-mail address and then type in some letters that will be displayed (this is a security measure). Then, you’ll get an e-mail asking you to confirm your subscription (this is called “double opting-in”), click the link given and you’re set!
