In case you are wondering, SiSu has uploaded a PPS (power point slide
show) in the 'Files' section.
You would need InaiMathi Tamil font and Naidunia Sanskrit font needed
for proper display. Here are the links for these fonts:
InaiMathi --> http://www.tamil.net/people/kiru/inaimati.zip
Naidunia --> http://www.naidunia.com/font/naidunia.exe
Here is how you install the fonts in Windows:
Step 0: Extract the downloaded fonts to some folder
Step 1: Goto Start-->Settings-->Control Panel-->Fonts
Step 2: In Fonts dialog box: File menu
Step 3: Click Install New Fonts
Step 4: Specify the folder where the extracted font file are.
Step 5: Select All fonts
Step 6: Click OK and your are done.
Hope this helps.
