RobOHara.com supports e-mail updates. If you sign up for this feature, my website will automatically send you an e-mail each time I post a new blog entry. Your e-mail address will not be used for any other purpose (I cannot see them). Once you have subscribed, you can change the type of message you receive and how frequently you receive them. You can also unsubscribe yourself from the list at any time. Again, I can’t see the list and it doesn’t notify me when people unsubscribe, so it won’t hurt my feelings a bit.
(If RSS Feeds are more your thing, I have one of those, too.)
