Thanks to Andrew of WebhostingHub, wp-ses is now translated in spanish.
The new version 0.3.42 ships with the required file. Nothing to do if your blog already is in spanish (define (‘WPLANG’, ‘es_ES’) in your wp-config.php )
Some strings are yet to be fixed within the plugin’s code, but it’s already great.
Thank you, Andrew !
If you want to translate the plugin in your language, just use poedit with the included wpses-xx.po, and send me the translated file.
It will be included with the next version (and you’ll be given proper credit).
