SlideShare is a free service for sharing presentations and slideshows. You can upload your PowerPoint and OpenOffice presentations, tag them, embed them into your blog or website, browse others' presentations, and comment on individual slides. It's a great way to share your ideas with others, or to learn from other people. And it's free >>>
Now you can filter slideshows by language. You would also have to specify a language for every slideshow you upload.
Now you can add users as your contacts; this lets you subscribe to their latest slideshows from your account.
you can also get my uploaded slide from here
