Photoshop Tutorial Listings

On the same kind of note, I'd like to put together a "Go To" Listing" of Photoshop tutorials that our readers could visit to brush up on anything Photoshop. I'm not looking for any site, but say 10 of the premiere sites for this information. Here is a sample Listing:
1. NAPP - The National Association of Photoshop Professionals
2. PhotoshopUser TV
3. WikkiVid Photoshop Tutorials
4. Photoshop Gurus
5. Photoshop CS3 Killer Tips
6. Photoshop Quicktips
7. Planet Photoshop
8. Tutorial Index - Photoshop
Let me know if you have any favorite that we could add.
