is anyone planning to take part in the global day of action on saturday?

also, i've been sent this by a few friends:

Hi, have you heard about the crisis in Burma?

Burma is ruled by one of the worst military dictatorships in the world.
This week Buddhist monks and nuns began marching and chanting prayers to
call for democracy. The protests spread and hundreds of thousands of
Burmese people joined in -- they've been brutally attacked by the
military regime, but still the protests are spreading.

I just signed a petition calling on Burma's powerful ally China and the
UN security council to step in and pressure Burma's rulers to stop the
killing. The petition has exploded to over 200,000 signatures in a few
days and is being advertised in newspapers around the world, delivered
to the UN secretary general, and broadcast to the Burmese people by
radio. We're trying to get to 1 million signatures this week, please
sign below and tell everyone!

Thank you for your help!

i've signed it as i've signed other e-petitions in the past but i have started wondering just how effective they are. any thoughts?
