If your SkyVault account is an Administrator account, then you can make yourself a site
   manager of any site that you're a member of.
  Note: Users who aren't a SkyVault Administrator don't have this option. They need to request a
    role change from an existing site manager.
  
    In a site click 
 then
      Become Site Manager.
   
  You are now a manager of the site. You'll see that you have additional options available
   when you click 
.
