Added files:
/loncom/interface createaccount.pm
Log:
Bug 5558. Visitors without a LON-CAPA account can create one, using an e-mail address (sends a URL to the address provided, which needs to be visited to complete the process), or an institutional login (authentication required).
Requires Authen::Captcha perl module to discourage robotic account requests.
Work in progress.
