Thread:Project talk:Support desk/create user groups and add members to it

Hello I have created 5 users ,user1 ,user2, user3, user4, user5 Here user1 is the admin user2 is a reviewer user3, user4, user5 is the editor Only user1 should have all the rights in media wiki ,,like he should be able to edit,delete ,create user groups, add members to the groups etc user 2 should be able to only delete ,edit the pages in media wiki and user3, user4 ,and user5 should only have the privilege to create a post but should not have the privilege to publish it without the consent of user2

I have created the user ,but i don't know how to create user groups as admin,reviewer and editor and assign these members to its corresponding user groups Stuck here for sometime, Hope i'll find a solution
