Vishal,
OK, looks like you should contact them by phone. The e-mail addresses on
their web site are apparently out of date.
Please read the letter I wrote as a guidline.
I'd actually prefer that you call them tommorrow, if possible. See if you
can reach Shridhar as well. If they are unresponsive, I will need to
contact other publications to do some damage control, and sooner is better
than later.
