I asked:
When I'm sysop, can I give these rights to the other Wikipedians?
It seems I could, but I can't.
When I click on "Edit user rights" on http://test-de.wikipedia.com/wiki/special%3AListUsers
the script says:
Special:Edituser Es gibt keine Spezielle Seite "Edituser"!
(There is no special page "Edituser"!)
