Hi all.
After a short talk with River and DaB, I have added a new rule to http://meta.wikimedia.org/wiki/Toolserver/Rules:
If you operate a bot from zedler, it must comply to the rules of each wiki it accesses. It must not edit anonymously - it may get blocked, and all other scripts on the toolserver along with it.
A few days before, DaB had added another one:
It is not allowed to ask a user for his/her password of one of the wikimedia-projects.
A system for user authentication using wiki accounts is under development.
As a reminder: DO read the rules page I linked to above. If you already have, do it again. Thank you.
