I live in Canada, and calling my member of Parliament won't do a damned thing.
BUT, if you live in the US, NOW is the time to act. The legislation has been introduced to congress and originates from the chairman of the committee that is most influential in the specified area.
BUT its life or death rests in the votes of you local representatives. This is the time to call your congressman. This is the time to call your rep in the senate.
Good luck to my American brothers and sisters in this one.
I will post the PPA announcement on my other page.
