Oops... sorry if I sent this twice.

   Would Kasumi call him Ranma-chan? I thought onna-Ranma was more 
standard Japanese.

Well...in the anime, at least, they differentiate (I thought) with
Ranma-kun and Ranma-chan... that's what I keep hearing in the subs,
anyways.

In the manga, everyone calls Ranma either Ranma or Ranma-kun... Kasumi
calls him 'Ranma-kun' in both forms. The only person that's ever called
Ranma 'Ranma-chan' is Happousai. I've only even noticed Happi calling
Ranma 'Ranma-chan' in the anime, too... But I don't take much notice of
stuff like that in the anime, anyway... Not Takahashi enough... ;p

Kun-chan...
