Trying to edit user to enable sharing

I am trying to follow this guide:

http://support.apple.com/kb/HT1812?viewlocale=en_US

Here are the steps:
1. From the Apple menu, choose System Preferences. Did this
2. From the View menu, choose Accounts. Did this
3. Select the account= Selected my admin account
4. Click Edit User. - Here is where I have the problem - I can't find the "edit user button"! I feel ridiculous. I have the admin account highlighted. I looked in all the menus on top (apple, system prefs, edit, view, window and help) and within all of the buttons on the "accounts" window. What am I missing?

If you're editing your own account (the logged-in user), you must take the additional step of typing your password in the Current Password field and then pressing Return. This is not required when editing other accounts.

I did check the "+" button and entered my password, now the lock is unlocked.


Thanks for any help.

I uploaded a pic of the window.

 

Thanks for the tip = I read that, but it was the "log in from Windows" that threw me. I wasn't trying to 'login from windows' i was trying go login on my mac!

In the end I connected using a direct ethernet connection and that worked out really well.
