Today I showed Sheila at the Harambee Centre how to turn a Word document into a sensible email questionnaire. We just went for copy and paste from Word into an HTML email, then asking people to reply and fill in their answers.
Outlook 2000 has a nice feature that if you type within a reply to an email beyond the end of lines of the replied-to message, then it marks your text with your name and a special colour. This makes it much easier to read the responses!
