I feel like I should know this, but...... I have a new user added to my site. She has a username, email, and her role is subscriber. I don't know how this happenned. My site has 'Contact Us' page and all posts allow responses with name and email. In my settings under "Membership" I allow anyone to register. Prolly a feature of my theme. But I have no membership page. Is this someone subscribing to RSS feed?
