I think that /ignore should work on global, far too often visitors and such come on to World of Minecraft and spam up the global chat while <WM> is off busy with other things. I know that i can easily just /global off but i enjoy talking on global and building loses it's touch if u cannot talk to someone while doing it. I don't think that the coding for it would be too difficult (although i know nothing about coding..) and it would be greatly appreciated.
