By text-only, I mean take your Word/PDF/HTML press release, conference announcement, and call for papers and copy and paste the text into the body of the message. To be most effective you want to send in nicely laid out text (text with white space and the web link spelled out as in http://www... in plain old text). When it is passed on to thousands of people via DoWire it will then be in the lowest common denominator format and reach far more people in an effective manner.
