Due to construction work in our building, our server will go down on feb 18th and 19th, so no mails to the mailing list will be forwarded these days. We apologize for this inconvenient.
PS I moved the mailing list archive to the link http://iem.mhsg.ac.at/mailinglists/pd-list/
and there is also a small website about pd at http://iem.mhsg.ac.at/pd (hope it will grow :-) )
