Pale at A Creative Revolution says 'Drop Everything' and email your MP (if in opposition, of course) to support the Lib/NDP/Bloc coalition.
I emailed my MP, Olivia Chow, and got a reply in about 30 minutes. Makes me think she's getting a few such messages.
Then I emailed a bunch of friends to ask them to do the same.
Got this zinging back from one:
'Done that. Yes we can!'
