GA here, I had forgotten, but we have a NW Regional Hash Google Group. No idea how that can be useful after FB and everything else, but just to let you know that if you see this email in your inbox or spam... then you are a member! For what its worth :)
If you have any ideas or opinions please let me know! If you know anyone who needs a dhash email, needs to update theirs (ie changed email address), or wants to join just email me.
