The website of Hungarian Unitarian church, in Hungary and Transylvanian Romania, points out three free and open source software projects — thank you, Google Translate! I use all three, and recommend them, too. Links to the English software sites follow:
- OpenOffice.org office productivity suite (though I use the LibreOffice fork more these days)
- The Sword Project Bible reader. (Using BibleTime as a front end.)
- Firefox browser
