Ensuring Documentary Access

In the middle of Colmar and Bro is sending some files to work but had them in ‘Docx’ format which he could not open in the internet Café. Made me think that I need to make sure that the questionnaires I am sending out are going to be used by people with a lot older versions of Microsoft Word then they are using in France so I had better make sure that the questionnaires are in the simples ‘Doc’ format possible or I am artificially limiting my sample. Such are the issues of access that could adversely affect my survey.
