I'm using WordPress for a local community activist website, and we're using the user registration system to have people sign up as members. We'll be sending them occasional email alerts, letting registered users comment on things, etc.
But I'd like people to be able to remove themselves if they want, so they can stop receiving our email alerts if they want.
Is there any way that low-level users (Subscriber Role) can delete their own accounts? If not, how might I go about enabling that for them?
