Three Selectable User Levels

1. Starter sections are like "executive summaries". These brief introductions with simplified and synthesized content are ideal if the reader has little time and wants to keep it simple.
2. Essential sections get the reader up to speed quickly and are a must read for beginners. But even for advanced readers they are a nice refresher before diving into the advanced sections. Image editing tutorials in the essential sections are based on Adobe Photoshop Elements 2, 3, 4, & 5.
3. Advanced sections build on the essential sections and are more in-depth and detailed, and technical at times. Image editing tutorials in the advanced sections are based on Adobe Photoshop 7, CS, and CS2.
