Quite a while ago Kat recommended a newsletter from about and Sue Chastain. Thanks Kat there are some interesting hints and help in there.
When it came this week, it mentioned a beginners Photoshop class. As I looked thru the outline, I thought some of the newer photoshop users would find it helpful. It's meant to be 8-10 weeks long and you can work at your own pace. You can sign up here.
