Grassroots Response to .doc E-mail Attachments?

LurkingAbout asks: "Maybe it's just me, but it feels like people are sending Word .doc files as attachments more then ever. Typically it's a friendly acquaintance who doesn't realize that .doc is one of Microsoft's ploys to force the few remaining holdouts, like me, to shell out for a copy of Word (or better yet Office). This morning it was the director of my daughter's preschool with the monthly parent newsletter. I've taken to responding with a polite-but-educational message requesting that the sender save the file as RTF or HTML and resend. If I'm feeling long winded I sometimes go into a diatribe about the Evil Empire. Today I started thinking that maybe there's an opportunity for some grassroots organization here. Maybe a concise well-written boilerplate paragraph for just this situation? Or a link to a web page to help educate the masses who think .doc is like air. What do other Slashdot readers do in this situation?"
