I teach web design and development. http://www.tinkertech.net has tutorials for dreamweaver, flash, photoshop, etc. http://www.robinsblog.com has tutorials and resources for web design and related subjects (this is a blog for my students). There is a lot of stuff on Firefox there. I have an artilce on planning your site on tinkertech I think...It's hard for me to remember where I have stuff. Anyway, I am planning on updating it because I am going to start teaching a high school class next week and we have to talk about web site planning. Let me know if you have questions.
