Years after I shelled out money for Adobe Acrobat, I found out there are several open-source, freeware programs that create PDF files. I could have saved my money if I’d known. It’s always been difficult for me to find a good freeware program to do what I want, and I tend to end up paying for software. I knew that SourceForge was a good place to look, but I felt like I was blindly groping in the dark. Well now that has come to an end. Wikipedia—a wonderful site if you’re not familiar with it—has a categorized list of all known open-source software, most (if not all) of which is freeware.
