whois databases and null fields

[Timothy Brown <tcb () ga prestige net>]

Hey, folks.  Maybe a dumb question.

How does any registrant with null fields for their contact data manage
to modify their registry records, outside of sending a letter on their
company letterhead?  For that matter, how do they get bills from the
aforementioned registry? :)
