Does anyone know if there's a Michigan metal or post-metal forum?

Hey everybody.....just curious if anything like this board exists within the metal scene. I'm booking the Rosetta show Saturday and besides flyering record shops and stuff I'm not really sure how to get the word out to the more metal or post-metal crowd. Any tips would be much appreciated. Oh yeah, come to the show Saturday, it's gonna rule!

I can post it on a metal board I run called Reeelapse, but I doubt that many people there that would go wouldn't already know about it.
