Administration Area in Asp.Net MVC

My question may be obvious but I'd like to build a well-designed web application. As for any administration area, the admin should be able to list/create/delete/modify users, articles, posts, etc...

I'd like to know what is the best way to design the application. Should I create a controller for each one of those items (/Users/Create/id or /Posts/Delete/id), or create all of the action in my Administration Controller (/Administration/CreateUser/id or /Administration/DeletePost/id) ?
