XP Sinhala Language Pack
Jinath has posted some screenshots of Windows and a Google page with the Sinhala Language Pack installed. Microsoft released the beta version of the Sinhala Language Pack to be used in the Tsunami aid programs. We MVP's got a beta copy as well to test out and provide feedback on. Hmm... I'll need to learn to read Sinhalese first before I can give any feedback though.
If you haven't seen the Sinhalese Google check it out here http://www.google.com/intl/si/
