Spam forces email confirmation on registration

After a long time using only the honor system, openacs.org has been forced to turn on email confirmations for new registrations. This means new registrations will get an email where they must click a link to confirm they are a real person.

Over the last few months spam accounts have been created to enter postings into forums and even bugtracker and this is the simplest solution to combat this problem.
