[sympa-translation] Re: [sympa-users] Re: [sympa-announce] New sympa release 5.0

[Moni]

I've tried to get there, to start the translation 
of sympa in occitan
but I couldn't get to start the translation, 
I had this message : 

Sympa has not yet been setup for translation through Rosetta. If you
have the latest PO Template for Sympa then you should ask administrators
to setup this product sending an email to Rosetta's mailing list . You
should give them the URL to the .pot and .po files. As soon as that has
been done you will be able to start translating.

I wish to translate sympa from french to occitan, 
could anyone explain me how I should start? 
(and if someone could explain it in french it woulb be even better for
me, but anyway I'll do my best to understand the answer even if it's in
english)
