As a network administrator, I noticed that the main reason people are afraid to send OpenDocument files by e-mail is the assumption the other party uses Microsoft Office and can't read them.
If your organization use OpenDocument day by day, please contribute to demolishing this myth (which is very beneficial for Microsoft) by letting people know: insert your business name in the list of OpenDocument and OpenOffice.org users at http://wiki.services.openoffice.org/wiki/Major_OpenOffice.org_Deployments
For my fellow Romanian users, a "national list" is also available (very incomplete): http://www.openoffice.ro/wiki/ODF_in_Romania
This is not only for showing the entire world OpenDocument HAS a significant user base, but to know about each other.
