The Pirate Translator was a widget offered by Pirates Online. You could simply type in any phrase you want to "pirate-ize", or choose from a list of useful phrases they've provided, and hit the translate button.
You could click on the "GRAB IT" button to put the Pirate Translator widget on your social networking site! However, due to unknown reasons, the translator is no longer available.
All "Downloads" are from the official POTCO site.
