RE:C&R Brochure Ideas
Not sure about the format compatibility issue, but since it's a small document, it wouldn't be hard at all to redo in Quark. Yes, the layout should be such that it can be reproduced on a copy machine. Anything else and it just gets too difficult to disseminate.
Form follows function. I would suggest 8.5 x 11, printed in landscape, tri-folded. That gives six panels in total including a "front cover" (for an eye catching graphic), while the "back" might include a return mailing address for sending in contributions, requests for inclusion on the mailing lists, etc.
What about the other panels? Content? Message? Name for the organization? These are issues that still need to be hammered out. The layout should be secondary.
