We, the undersigned, request that the Open University require all software needed by students for study and/or assessment purposes to execute on all major desktop operating systems (i.e. at least recent versions of Windows, Mac OS/X and Linux) unless it can be shown that no suitable cross-platform application of that type exists. We further request that the Open University accept any documents conforming to OSI document format standards (e.g. ODF) from students, in addition to any other formats that the university sees fit to accept (e.g. Adobe PDF, MS Word .doc or MS OpenXML).
