If there's already a Facebook page for PWG, then it should be pretty easy to set up a Twitter account as well. I don't use FB, but my understanding is that you can link it with a Twitter account and all updates on Facebook will also be sent out on Twitter (truncated to fit the 140 char limit, obviously) with a link to the full status update. An example of this in action can be seen in
Bryan Alvarez's Twitter page.
