Salam,
I came across a very useful online resource for learning languages, thought it might interest some people here.
Language Learning with Livemocha | Learn a Language Online - Free!
This is a online multi-lingual community + online language courses websites. Most language courses are free , others are not. But the best of part of the website is the large multi-lingual community, where you teach & learn different languages by interacting with different language speaking users.
