Gee thanks for the welcome! ^_^

 I think on #1.  you got them all... hmm... yup! i can't think of
anyothers!!!

#2. yeah i don't know what that is all about, and you are right that Soun
does absolutely nothing... i don't really remember the dojo ever being
challenged. hehe ^_^

#3. hmm... I guess, but i don't really think that Kasumi is the type that
would want to fight. and Nabiki, hmm... i don't remember her being
challenge, but then again, I didn't really get that far in the manga, and I
can't find ANY of the Anime so.... I don't know as much as I should.
:::sigh:::

#4. Yeah... I think your right, Ranma does learn a lot of usefull techniques
from Cologne, but I don't know.

#5. yeah... but look at the name, Anything Goes, you can do anything to beat
your opponent, it doesn't matter what it is as long as you beat them.
Although comeing from a Martial Artist myself some of the things they do can
be very insane at times. hehe ^_^

ok thanks for all the questions!! they were really interesting to answer!!
