WordPress admin page

Hai friends,

I created a website for one of my client, I created a user (Role- editor). But the problem is, when I logged with the editor username and password, the dashboard page contains a footer “Thank you for creating with WordPress.” and also a wordpress logo in the left top near to dashboard text, how can I remove both these footer and logo.? But I logged as admin, the above problem solves. Please help me

Thanks in advance..
