Those of you who are part of the Uber-Sekrit Wordforge FB group can join us in CAAAAAAAAAAAAAAHT! Otherwise, fuck you, lamers!
Your friggin FB Group-Chat-thingie would NOT stop popping up on me as I browsed FB, so I had to leave the group. Nice! Now you've driven me off, bastages!
It was annoying the piss out of me, too, until I figured out how to stop it. Go into the Group Settings for the group and uncheck the "Send me group chat messages" box.
