CreativeTechs, a mac support company in Seattle, is offering a 10 week course in Photoshop absolutely free! I have taken a few courses with this group and they do a great job. If you are just learning photoshop or just brushing up on your skills, there is something for you. They are also offering a bonus InDesign class also for free, so you can see what you are getting yourself into. If this 10 week course goes well they will potentially offer classes in InDesign, Illustrator and Dreamweaver. You can stay up to date with classes and get a few interesting tips by checking out there tip blog.
