(solved) Facebook flux into news ?

Hello,

Is it possible to use facebook flux of news into Contao's news (dedicating an archive for it for example) ?
And, why not, send back news created in Contao's to facebook wall ?

The must would be an existing plug-in but I can't find one.

Thanks

After some search on Contao' website (not only from Contao's BE) I finally found some extensions. I'll test them and come back if necessary.
