I can't seem to find a way to save files in CS back to older versions. I have to send files to outside vendors who are still running old versions of everything: Quark, Illustrator, and they don't even take InDesign. So my only option is to save as older Illustrator files. Right now, I have to keep going into v10 when I'm ready to send something so I can save it back. Any ideas? This is really time consuming!
