@ deAd: Your code has a chance of not working properly.  There is a chance that a contact sends a message between these events being called and that will cause problems.

@ Cookie: Where is the registry 'DisabledForxxxxxxxxxx' I have found nothing with a search of the registry with a search for 'DisabledFor'.  Also I wouldn't mind seeing the code optimised either, that was just the easiest way I could think about doing it.
