Why can't I sign up?
Some readers have mailed us to say that they cannot see any sign-up form on the page that's supposed to contain the form! This behavior is seen more in users who browse the sign-up form page with Mozilla Firefox -- although we can assure you that we check all pages on all browsers at our office, and everything works!
But we can't control what's on your machine -- maybe it's some browser extension that's preventing the form from showing up! In that case, we suggest that you use another browser, or sign in from another computer. If that's not an option, send us your sign-in details to us vide the feedback form, and we will manually sign you in.
