Changes of address.


Allow six weeks for all changes to become effective.
All communications should include both old and new addresses (with postal codes)
and should be accompanied by a mailing label from a recent issue.


According to 4 Sect. 3 of the German Postal Services Data Protection Regulations,
if a subscriber's address changes, the German Post Office can inform the publisher of the new address even if the subscriber has not submitted a formal application for mail to be forwarded.
Subscribers not in agreement with this procedure may send a written complaint to Customer Service Journals, within 14 days of publication of this issue.
