Subscription

I added the ability for visitors to receive e-mail notification whenever there's a new post.  Not that I think anyone's that interested, but I thought it was cool (yes, I'm both a geek and a dork), but also, if we get some political dialogue like before the 2000 election, I wouldn't mind my site being a forum.  Anyway, to sign up, it's at the end of the page.  (You can also unsubscribe.)
