I just noticed this on the wizards boards apparently there is a group chat every friday that discusses using "Planar twists" in your campaign. I thought it was interesting but Friday night is Warhammer Fantasy night where I live and I have to use my Vampire Counts army to conquer the old world rather than being online.
