Change Detection Test

I just added a change detection thing to the site on the right sidebar. I'm going to try posting something and see if I get any notification. I will endorse it fully once I've seen it in action a few days and see that it doesn't send notification on things that it doesn't need to, and make sure that it sends something appropriate when it sends notice.

Question: should I try opting everyone who is on the mailing list in and let them accept or deny if they do or don't want to be notified?
