There is no FB page because to have one would require members to either share a lot more of their personal information and lives than most of us are even remotely comfortable with or to create special, dummy FB identities to participate, which is technically in violation of FB TOS. You think ProBoard's TOS was oppressive? You ever even glanced at the Facebook TOS? You're practically giving Zuckerberg a key to your house and permission to raid the 'fridge.
Either way it's neither worth it or necessary.
