List rules and recommendations for users
1. To log in to the list, the e-mail address and the name of the name are required
2. This information is necessary for the functioning of the list and will in no case be passed on by the list operators to third parties
3. An e-mail address like micky@maus.xy may be funny, but is rather inappropriate to contact
4. Everyone is expected to sign their mail with the clear name; a signature like Mickey Mouse is unfair to the other list participants; Last name in (brackets) signals: I agree with the address "you"
5. a short idea (surnames, places) is desired but not required; helps to make contacts and share data
