There are only a few people in the world able to spot the mistakes I make and Vinod is one of them! He regularly writes in to point out typos.
I have been using his script converter for a year or so now and find it incredibly useful. Vinod has just upgraded his website and added almost a dozen scripts to his converter. This means that we can input in any 19 Indic scripts (including several versions of Romanisation) and output any of the others.
In addition there are a wealth of other resources - essays, translations and calligraphy.
