HawkWing.net is a great blog for finding tips, tricks and fixes for Mail.app — the default email client on a Mac.
The site was dormant for awhile, but recently woke up and has resumed posting.
Interesting side note, it’s run by Tim Gaden who is Dean of the Theological School , College Chaplain and Stewart Lecturer in Theology at Trinity College within the University of Melbourne. He also teaches Greek.

Customization of your Mac is one of the best ways to bring your personality to your Mac. And what better place for us to start talking about customization than with the About This Mac screen. Now some of you might not even know where to find this screen. So to begin click on the Apple logo in the top left, and the first item you will see is About This Mac

This is what you will see before you do any customizing.

What we intend to do is customize the image that you see in this screen. To start goto Finder and locate /System/Library/CoreServices/loginwindow.app

If you have trouble finding this folder you might be looking in your current users home folder and not the root folder of your computer. From here you will then need to right click and click Show Package Contents, and find /Contents/Resources/MacOSX.tif

Make a backup copy of this file to somewhere you can find it, so you can change it back if you want. Then find any new image you’d like, making sure that the new image is the same size image as the current one. When you have your image ready, just rename is to MacOSX.tif and place it in the location above.
To make sure it all works, just Logout and Login again to see changes. Here what I got when I was done. If you get a chance to customize your About This Mac Screen, we’d love to see it. Just post a link to the image so we can all check it out.
