Hi, I thought you might be interested in this website:
www.slidestory.com/

I am announcing that because I am speaking the German part there. :-)

If you like, check out the whole site - I am convinced it is great just for us who learn foreign languages:
- View others and create your own slideshows with narration
- Create a podcast in a very easy way, with transcript. (Transcript is possible in probably all languages, without problems. Not knowing anything about Chinese and Japanese, I haven't tested that.)

As this is my first post, perhaps a word about myself ... :-)
I am Martina, live in Berlin/Germany, and I take a big interest in internet, languages, multimedia, my cats ... etc. pp.
