You can! We are currently working with volunteer translators who are using the Google Translator Toolkit to make our tutorials available in other languages.
By using the Google Translator Toolkit, we upload the HTML file of each lesson and machine translate the content. We tweak the original text of the lessons to simplify the English to promote a truer translation. The Google Translate machine translation is far from a perfect translation, but it does serve to expedite the translation process, changing the review process to one of correcting and rewriting rather than translating from scratch. The Google Translator Toolkit allows us to invite contributors to collaborate on a document and preserve the layout of the lesson.
GCFLearnFree would be responsible for uploading the HTML files to the Google Translator Toolkit and machine translating the lessons. We would then invite you to collaborate on the document(s) to make changes to the document as needed. After you have signed off as having reviewed and corrected the content, we could then upload the translated content to our site, publish the lessons on our site, and then you would be free to link to these lessons at your site, preserving the layout and original structure of the lessons.
