What we can do is to make it compulsory to collect the DVD personally
if there is an ambassador in locality.
I guess this way, we may cut down the "I-request-whatever-I-get-free" people.

this is a nice idea... here in my locality i received a lot of requests from in and around my state... but the problem i faced was, some people asked me to courier the DVD's to their address (which was difficult for me) but some ppl met me in person and got the dvds burned....
Life is "just tryin out things to see if they work"
