Spanish Translation of Drupal's Private Message Module

I have completed the translation to Spanish of the Private message v5.x-1.8 module and related files and modules (privatemsg.info, mail_edit.module, mail_edit.info).

The current es.po translation file included with the module is quite old and inaccurate, which generates plenty of confusion when used.

I reviewed and updated the translation strings in the es.po file included with the module, then updated and enhanced them with the privatemsg.pot translation template file included; I then used the potx module to extract strings from modules and files under my sites/all/modules/privatemsg folder and proceeded to review, correct and complete all translation strings.

Since I'm not sure where to contribute back the completed Spanish translation file, I'm uploading it here and as an issue under the privatemsg module project page http://drupal.org/project/privatemsg and on the relevant groups at http://groups.drupal.org.

If there is a special place to upload module translations, please let me know.
