Because I hate you, we all hate you, everyone else is added on Facebook Alternatively it's because posting contact info on a public forum is kinda silly and asking for spam.
I'm "friends with" (or is it called Following?) this page for Lizardmen from Lustria https://www.facebook.com/groups/165711620130089/ It's not super active right now, but I wouldn't be opposed to seeing some spirited debates about PF in my Facebook feed.
I have never been a real big user of Facebook. I have started using it with my Malifaux gaming though. I sent a join request to the lizardmen Facebook page. Thanks for the link.
