For the Woopra WordPress Plugin version 1.3.8+ we have included the needed code for translations. You may download the POT file, which is needed for translating, here (http://svn.wp-plugins.org/woopra/trunk/locale/woopra.pot). This file on the SVN will always hold the current version translation file.
For any questions on how to 'translate' the POT file, click here (http://codex.wordpress.org/I18n_for_WordPress_Developers#POT_files) to view the information on the WordPress Codex.
Please send all translations (ziped) to 'shane [at] bugssite [dot] org' including, Your Full Name, Your Website. Send only completed translation files. Check this post to see if your language was received and validated.
Note: Subject should be 'Woopra Translation - <Language>' otherwise it will get rejected.
Thanks in advance for helping out the Woopra Community!
