Dear Bob, please send all categories postings for me to the address I used for this message till June 25. Afterwards, please send them to my new Hagen e-mail address "reinhard.boerger@fernuni-hagen.de". I think it would be easy to inform other people about these address changes by the categories network. Why do you object to this? Cordial greetings reinhard +++++++++++++++++++++++++++++++++++++++++++ Note from moderator: But of course address changes are welcome here! +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
