Hi Tom, yes our themes can be translated into any other language, including those which read right to left. On our
languages page you can find a link for instructions on how to create theme translations, and on the
ClassiPress language packs page you can find all existing translations including Arabic. To set up ClassiPress to read RTL you need to make some modifications to the stylesheet, and you can find a copy of this in the existing Arabic translation which was provided by the translator. There is also more information on the WordPress codex relating to
RTL language support. Thanks :)
