Thread:Project:Support desk/Permission to edit pages only if that user belongs to that group

Hello All, I am new to MediaWiki, I wanted to know is there a way to allow user to edit a specific page only if that page is created by the user who is of the same group. For instance if user A who belongs to a group YYY creates a page XYZ, and the user B can edit XYZ page only if that person belongs to YYY group.

Please let me know what setting I need to make to achieve this.

Thanks Chethan K
