This works like a charm:

--8<---------------cut here---------------start------------->8---
(add-hook 'org-after-todo-state-change-hook
	  '(lambda ()
	     ;; remove the scheduled date/time if present as the activity is no longer mine
	     ;; based on a suggestion by Manish on the org-mode mailing list
	     (if (string= state "WAITING") (org-schedule t))))
--8<---------------cut here---------------end--------------->8---

Thanks again,
