I just translated the plugin into Spanish. If I leave the .mo file in the plugin language folder, like this:
The whole admin part gets translated appropriately, but not the front part. I'm having a difficult time trying to figure out where to place the file so both the admin and front are displayed fully translated.
By the way if you would like to include the Spanish translation into your plugin, let me know and I'll send you the .po file so a few Spaniards can enjoy your great plugin!!!
