All players on Nostalrius should contact there local/national tech/gamer news sites.
I think It's important that the gaming community learns that Activision Blizzard chooses to "attack" a group of people who only want's to recreate a non-profit version of the great game that World of Warcraft used to be.
Perhaps Activision Blizzard changes their mind if it gains enough publicity.
News sites that already has written about it:
