The landing page at http://schooltool.org is a static HTML page.
To create a local translation, you can simply Save as... the HTML source from your browser, translate the body text, and send the file as an attachment to Tom Hoffman.
If you’d like to use bzr to help track changes made to the site over time, you can check out the sources to the pages at:
bzr branch lp:~schooltool-owners/schooltool/schooltool-org
bzr branch http://www.schooltool.org
We will take care of deploying the translations to the web server.
