Internacionalizationin Pier

Hi folks, I have a couple of questions about Internacionalization in Pier. I am developing a website and I would love it can have multiple languages (spanish, english, and so on). My "final user" is able to add posts or leave comments for example. So, I see two thinks I should care: 1) Pier comments: can this support multilanguage ? For pier components I refer to the html output of the components. For example, when you add a post, you have: "title", "author", etc... 2) My own page text. I have several pages with text. Which is the best approach to support multilanguage for this ? Any tip is welcome. Cheers, Mariano
