After the list has been abused to send commercial messages I have configured the software to restrict postings to members of the list. Thus only the maintainers will be annoyed by spam messages :-( This means also, that your contributions also must come from the address which is registered on the list. If someone needs sending access for another email address, please let me know. I'm sorry for any inconveniences, Klaus -- Klaus Guntermann <guntermann@iti.informatik.tu-darmstadt.de> FG Systemprogrammierung, FB Informatik, TU Darmstadt Wilhelminenstr. 7, D-64283 Darmstadt
