All our plugins have been developed following SocialEngine's standards, and are easily translatable via the "Layout" > "Language Manager" section of the Admin Panel. You may follow the easy tutorial for this in the SocialEngine knowledgebase over here: http://www.socialengine.net/support/documentation/article?q=153&question=TranslatingChanging-Phrases-with-the-Language-Manager.

We have also collaborated with some localization service providers like Streetlamp 360 for good quality translation of our plugins into different languages. They have recently released Italian translations of some of our plugins, and will soon be releasing Italian translations for all other plugins. They will also be translating our plugins in Spanish and French.
