	If you wish your message to be taken in jest, I recommend that 
you sprinkle some smileys (e.g., ";-)" or ":-)") throughout. 
Otherwise, people are likely to take you seriously.

	It is not possible to determine that number.  Just the 
delegations alone change quickly enough that you couldn't possibly 
tell, even if you had somehow managed to get an arrangement with 
every single other person on the entire planet that allowed you to 
see a complete copy of all their zones.

	You'd spend too much time walking the tree and it would change 
far too many times during that process.

	Feel free to give it a try.  Please let us know how it works out.
