Yes, Ed Lafrance is one of the talented consultants on this list.

I believe it basically:

If "email_confirm" doesn't equal "email" then

&calc = delete $CGI->{email_confirm}; 1;
which deletes the email_confirm value, so when the next check comes along:

email_confirm=mandatory Email_confirm doesn't match email.
It will ring false.

I am not sure what the "1" is for.
