shows a link to the group's wiki (groupname . ' wiki') if it exists. Since most of them are no longer used (except gods, pollsters, maybe cabal, others?), seems like that can change. They could all be removed, or replaced with a link to the scriptorium, or the deprecated wikis could be renamed with ' (deprecated)', or we could add a wiki node id column for usergroups and use that if set. Any opinions?
