Hello Werner I don't remember what I gave you last week but you can access everything I have prepared for the Friday lessons at http://members.optusnet.com.au/~skijat2/start.htm. Let me know if you have any problems or comments. We have a mailing group which is not very active but anything related to the projects can be posted to psp-pwg@xxxxxxxxxxxxx and with any luck you will get an answer from someone fairly quickly Regards Brian
