Over at TIBM.org we have just updated our Nepali Language Learning Resource page to include a new and really great free resource. You can see the description below of the Nepali Primer produced by Digital Himalaya. Along with the other resources we've included on our site, Nepali-language students should run, not walk, over to tibm.org.
Nepali Language Resources: "1. Nepali Primer - This is a basic introduction to the Nepali language that has been produced by the Digital Himalaya Project. If you are just getting started with Nepali, you will be hard-pressed to find a better, free online resource."
