Hi 
Welcome in!! :) You already have requested a user-name and login for Alfresco, hopefully someone will be able to set-up your login and someone also set-up an ODFAuthors account.
If you can translate from French to English, even if it's not perfect then you might like to start translating the Faq from French to English
http://wiki.documentfoundation.org/FR/FAQ
to
http://wiki.documentfoundation.org/Faq
Alternatively the Documentation pages on the wiki might be helpful but could use some work to make them easier to understand
http://wiki.documentfoundation.org/Documentation
The advantage with working on any of the wiki-pages is that you can register yourself and start straight-away. There are people that monitor and have an over-view of edits so don't worry if you don't have much experience yet.
Hopefully you can get to the proper official guides fairly soon but it takes us a while to set-up accounts in Alfresco and ODFAuthor
Good luck and regards from
Tom
