Check out this old post on my blog for links to free design software.
Also, here's a link to the companion website for our text, Document Design.
Remember that Photoshop (and/or GIMP) and Dreamweaver (and/or some other WYSIWYG editor) are on many of the computers in JM 103. Over the course of the semester, we'll be using these programs to produce some of our class assignments, so if you want them on your personal computer, these links will help you get them.
