Maintain Nepali Unicode. Thanks to them.. now typing in Nepali is very easy.. and consequently lots of sites/blogs in Nepali is emerging. Recently, they launched NepalLinux 1.0 (Linux OS in Nepali) on 22 Dec, 2005.

You can download Nepali Unicode from their site by clicking here

Also.. i found some good Nepali to English Dictionaries.

Cornell's Nepali-English/Nepali-English Dictionary
Mark Turin's Thangmi-Nepali-English Dictionary
Bruce Adcock's 420-word Unicode Nepali dictionary
Nepal Homepage's English to Nepali Dictionary
Ralph Turner's Comparative Dictionary of the Nepali Language

There are a handful of interactive language learning tools for Nepali which are worth exploring:
