Custom Subscription

So, I've given myself (and spared you) three days to try and get this to work. Didn't happen.

I created a Custom Subscription (Node Type: Announcement) and cannot get it to send email OR queue. I can subscribe to content types, like Page, Story, etc. I have a custom content type, Announcement, that I want people to be able to subscribe to. Any ideas of why this isn't working or what I can do to troubleshoot?

Like I said, I've spent three days reading threads, tinkering, checking this and unchecking that, nada. Oh, and this framework doesn't provide much in the way of log entries :\
