I am new to MediaWiki and couldn't find the answer
to my problem in
the docs. Maybe I was just blind but I hope someone here can help me.
The real way to do maintenance actions is of course by using eval
interface:
flu:phase3 midom$ php maintenance/eval.php
User::newFromName("Eviluser")->addGroup("sysop");
Logout, login, here you are.
