WpCandy has released an awesome PDF which contains helpful information related to developing themes for WordPress. The cheat sheet includes the following:
- Basic Template Files
- PHP Snippets for the Header
- PHP Snippets for the Templates
- And Extra Stuff for WordPress
The resource has been translated into Spanish and Romanian in case English is not your native language. At any rate, click here to view the PDF within your browser. Alternatively, you can right-click and save the file to your desktop.
Considering Matt Mullenweg and company are considering a WP-Theme Marketplace where unique theme designers can be paid for their designs, it might be a good time to pump up that WP theme knowledge.
Thoughts and Insanity From Jeff 
Thanks for the heads up Jeffro. This will definitely come in handy!
How was your weekend mate?
@Mike The weekend was good. How was yours?
Not bad. A mate got me The Orange Box (Half Life 2) for the 360. Still looking for a place to rent, and I bought a fish tank to have some pets.
Although fish, with their 3 second memory are a bit of a pseudo pet.
I missed work on Monday, which was fantastic!
