I just realized I have to manually trigger the notifications to go out. It's not a problem, but I'm sure the few people who signed up to be notified when I post to this site have wondered why they have never received anything. Everything has been working fine, I've just been neglecting to click the Send button like an idiot. So spread the word, and if you haven't already signed up (it won't let you sign up twice with the same email address, so don't worry), sign up now!
Plus, if you don't sign up, and I feel you should, I can add email addresses on my own-- muwahhahhahah!
