I play at thewake. One of the muns that play there actually does play Shadow regularly outside of the game. He's on Haitus right now though, but if you asked him he might be willing to musebox. (His journal is doomsblood. He also plays Shadow (and occasionally Lancelot) at his other game, 3step_paradise.)

The only other Shadow journal I've seen plays at a game called Dragons haven. I see them around occasionally on Dear_Mun so maybe you could poke them as well? I was thinking about poking that game myself..
