Greetings Earthlings, Just wanted to let you all know that my Sky Lights <http://heimhenge.com/skylights/> blog now has a subscription feature. It was never my intention to inform you every time a new column is posted (unless it was especially interesting or important) ... kinda' hoping Sky Lights "sells" based on its own merits. Not that I'm selling anything. But I did want to point out the new "Subscribe to Sky Lights" button in the top right menu. Simply enter your email address, respond to the confirmation email, and you'll receive an email whenever a new column is posted, usually on Mondays. How easy is that? Enjoy.
