Organizator of the two european tcl/tk user meetings in Hamburg/Harburg:
I'm author of a bimonthly tcl/tk series in german Linux Magazin http://www.linux-magazin.de/ called "Federlesen". This is pun on the feather (german Feder) and the german saying "Ohne Federlesen" -> without hassle.
Sources for these articles could be found on the website of the Linux Magazin.
Other sources mostly for Tcl and Corba could be found on my homepage http://www.groy-groy.de/czerbst/tcltk.html
