The knowledge foundation at Chennai has mooted
attempts to start the India chapter of the Wikimedia

At a more fundamental level, we are also thinking
of tying up with schools to use the literature
available in Wikipedia for classroom education,
Mr.Kiruba (founder of Knowledge foundation).
As many schools do not have full fledged computer or
internet access, we may offer them CD versions of
regional language Wikipedia. That will also potentially
create more regional language wikipedians (
contributors of
articles to the online encyclopedia
) in the futurePage 22
