I have a wikifarm of 3 wikis, and i'm trying to create a "Steward" user group that can change rights on all Wikis. So I assigned the 'userrights-interwiki' right to the steward group (on the "meta-wiki") and gave myself steward rights, although I don't know how I change rights on other wiki's because my Wikifarm is using a shared database with 3 table prefixes. Is it possible to change interwiki rights when I'm using prefixes instead of databases?
