I just posted the handbook for Photoshop 203.
If you have previously purchased this handbook, you can download it now. If you haven't bought it yet, and you've taken the PS203 course, it makes an EXCELLENT reference to look back on if you can't remember how to do something. It's only $5.99 and you can get it here:

As of right now I'm not planning on writing handbooks for Photoshop 204 and 205, but I've added them to the Waiting List. If enough people want them, of course I'll make them.
Waiting List
Enjoy.
