Have I got the perfect place for you! I am a member of an online group on Paltalk (a voice chat program that has a free level of membership). Our group is called Developing Webs and it is located in the PC/Hi tech area of Paltalk.
Anyway, our group holds online tutorials for Photoshop, Flash (currently), PHP, etc. We have a wonderful room owner who goes by Ladymindy. She gives her time freely, and she is a great teacher. I personally have taken some of her classes, and even though I had used the program prior to the class, was able to learn a lot from her in class.
If you are not into voice chat (Paltalk is not like the others), I suggest you check out our group web site. This is also owner and maintained by our illustrious leader, but has many contributions from the rest of the group. You can check out our site at
www.developingwebs.net . There are many tutorials for many aspects of web design, with a whole section on Photoshop. The tutorials in the Photoshop sections cover various levels of competency. There is no fee for these tutorial, and you don't have to become a member. But if you do join, it's free also. It's a great all around site. Check it out. I am sure you will be pleasantly surprised!
