Might be some people just ignoring the fedora list, but attending is required but it is not implies that Ambassadors are sleeping.
As I know there are good community members from your country (India).
Specially Rahul Sundharam [1] giving good a contribution.
Hope you met him at
FOSS.IN 2007 :)
and the Punjabi Community too. Amanpreet Singh [2] and Jassy Phulewala [3].
both of them working for spreding FC on Grate Panjab part from their usual Fedora contribution.
I think this is good time to motivate all the Ambassadors .
Good leaders have a talent of getting the support from ANY_BODY ;-)
