I've localised PrintFriendly into Finnish. How can I use it? It didn't work by placing the translated PrintFriendly-fi.po file into "wp-content/plugins/printfriendly/languages/" folder.
I'd like to use it in a multilingual multi site environment, so I'm planning to translate / localise into many more languages :D
By the way, the original version I'm using under WordPress 3.5
