* do_identify)
* validate_user (adding a collide timeout on the real nick)
* cancel_user (deleting a timeout on the real nick)
* do_register (checking whether the real nick is registered)
* do_drop (dropping the real nick)
* do_link (linking the real nick to another)
* do_unlink (unlinking the real nick)
* chanserv.c/do_register (setting the founder to the real nick)
* plus a few functions in users.c relating to nick creation/changing.
