I've implemented a basic subscription service that will automatically send you an email, each time I write a new post. Scroll down to the bottom, left-hand corner of any page, enter your email address, and hit the Subscribe button. You'll receive a confirmation email.
This is brand new, so please let me know about any glitches. For now, this service will just keep you updated about new content, but I may add a newsletter in the future.
*In order to activate your subscription, you need to open the confirmation email and confirm your email address.*
It's totally free, and you can unsubscribe at any time. I won't share your email address with anyone.
