Hi Zoya,

Authors, Readers, and Submitters shoudn't have the capability to edit any queries. The only thing they can do is to view the data of the queries, but they have no rights to view the SQL code that the query is comprised of. Those right are strictly for Admins via the Query Browser.

With regard to preventing Admins from editing wikis, the only other possible thing you could do is to hide the menu options for the wikis via CSS code. However, in doing so, you will also be prevented from seeing those options as well, which would make administration more difficult.

Regards,

Jon
