This is a fantastic initiative. I just saw the video and it's a really well put together.  Even though it's Odia centric, I'd really advice everyone in other language projects to take a look at it.  It shows how to edit, basic wiki markups, etc. - in an Odia context.  I love the call-out buttons!

couple of comments. 

a) Not sure if it's designed that way, but I don't get sound when I saw it.  If it's meant to be that way, that's great because it is really clear even without a voice over

b) Would be great if you provide access to it in on the odia wikipedia homepage,  all you social networks (eg, you odia wikipedia facebook page, etc.), use it in all your outreach sessions (which I'm sure you're planning) and socialise it far and wide!

This is really really really impressive, Subha.  Hats off to you - and the rest of the Odia Community. 

All the very best!
