I have not figured out how to decode documents that are sent to me in a "wps" format. I assume that this is some sort of a wordperfect (or as we often call it turdperfect) format. It seems apologetic to ask the sender to resend the document in their mail program, not as an attachment "because I'm using a Mac" . It is as if I am admitting some sort of lesser system that requirews their special attention, and it would further concern them if they were thinking of switching..... What is the proper etiquette for this social faux pas?.
