                I most definitely second that!

                BTW, I have (like most everybody, I guess) some classes for 
elementary descriptive statitistics tasks I can contribute if someone's 
interested.

                I have some technical question, though. Since there are 
mightily few variations possible on the implementation of elementary 
functions, I wonder if we do not risk to impinge on the copyright of 
works such a "Numerical Recipes" (even if the concepts are of course 
not copyrighteable, the language is different, and the implementation 
is different but mostly amounts to some translation).

                I also have some code (CORRECTED from NR) for Kolmogorov-
Smirnov statistics I am willing to share (but the correction is 
somewhat ad'hoc so it would benefit from exposure).
