I think, the easiest way is to
1.) unzip OSSN 2.3 locally
2.) remove all directories and files except those one named "locale(s)"
3.) move your Spanish translations into the "locale" directories
4.) zip this directory tree
5.) upload the archive to the component store

That said, your archive should be structured like

components/OssnAds/locale/ossn.es.php
.... down to ....
components/OssnWall/locale/ossn.es.php
installation/locales/ossn.es.php
locale/ossn.es.php

An archive like that can be easily transfered to the server and unzipped there in one step without harming anything essential.

yes, i'm newbie in this project, but i love the idea. I did all components translated, but i dont know how distribute.

Thanks, Jose!

That's a good start. But please note, that each component has its own language file which has to be translated, too. Another one can be found in the installation directory.
