hi harold,

thanks for the article. I thought it might be relevant to mention the eLearning community where I ´ve been working on, http://www.palabea.net
we have a different approach as our competitors, but basically we use web 2.0. tools to create a space where multiculturalism and tolerance are encouraged with the goal of language learning.
feel free to try it (it´s free of cost ;))
feedbacks are welcome

best wishes

gorka
