I spent quite a while reviewing the material on this website. I found it very informative and helpful. I never did quite undestand what ADD was and how much of an impact it has on people. I was especially was surprised to find out that adults can have it too. That's not something you hear too much about. I think this website can definately help both teachers and students with learning about this.
I found it very easy to navigate around the website and get the information I wanted and needed, so I definately think that first time users will have no problem with it.
