The first draft of Chinese version "Free Software for Education"

[jerryxu]

Hello, everyone.

I'm new to the zh-cn-translators group. After reading the workflow.html,
I have attempted to translate the article named "Free Software for
Education"
(https://www.gnu.org/software/free-software-for-education.html) into
Chinese. However, I still don't know how to submit the translation.
Should I join the zh-cn-translators group on savannah first? Or, should
I do other steps?

Also, for the last part of the article, the article used "GNU Free
Documentation License", but I did not find a official translate of the
clarification( "Permission is granted... no Front-Cover Texts, and no
Back-Cover Texts"). 

Thank you!
