It seems all the sign up pages' sign up buttons are hidden.
The class attr is misspelled to klass. The button text is empty too.

In addition, I remeber it's possible for one email address to have more than one PythonAnywhere account. Is that correct? I think adding an search box to the allowlist page like the the one in the forum would be nice.
