Muy bien.  I only have three points to address.
	Why _wouldn't_ Shampoo tell her hosts/tenants about her curse 
(that self preservation thing should be a good motivator)?
	Character profiles would be nice for your creations :)
	Why do I think that Akane's arrival will complicate Ranma's 
'half-life' considerably ;)
