Create a "Sign up/Login" form exactly as Edublogs

Hi,

I want to create a "Sign up/Login" form exactly as in the edublogs.org (when I click login, I type username and passward to login). I want it in the top right of my home page.

Also, I want to show the links to the user Dashboard, his Blogs and Logout when the user is logged as in the Edublogs.

Which is the plugin to do that and how? I'm using multisite. I tried this link (http://red-team-design.com/simple-and-effective-dropdown-login-box), but it does not work.

I attached a print of the screen when I'm not logged and after the login.

Thank you very much.
