Hello there,
Can you please elaborate what specific issues are criticial for you regarding french ?
Obviously, page names and page content can be in French.
Standard confirmation emails are in English but very soon we will provide ability to customize them so you can write them in French. (a few weeks away)
Built-in forms and administration functionality are only in English for now. We have it on our roadmap for Q4 this year to add localization options.
