The congo Tutorial looks cool and really easy to read, except some mistakes on typing and writing. i am going to try to send a commented version back to you. Is this Tutorial going to be translated in french? I have some time these days and I can try to start translation so we can share this tutorial with french speaking folks. Would you be interested in doing it? i'll need the .xls version of the file then.
waiting for an answer.
Take care
Stephan
