- Where self-creation of accounts is enabled for institutional log-in and
also e-mail address as username, call to &javascript_setforms() needs to
occur from within print_dataentry_form() so that args required for CAPTCHA
validation are passed (when ReCAPTCHA or CAPTCHA are in use).
1: # The LearningOnline Network
2: # Allow visitors to create a user account with the username being either an
3: # institutional log-in ID (institutional authentication required - localauth,
4: # kerberos, or SSO) or an e-mail address. Requests to use an e-mail address as
5: # username may be processed automatically, or may be queued for approval.
