Let's recap, ForumViewer.
You: "And this is in Europe, which affects probably very few people on OCN."
Me: "Actually, there are quite a few members here who live outside the US."
You: "I didn't say otherwise. But there are clearly more Americans here, which is what I said."
Me: "You did not say anything about Americans, just that 'Europe affects very few people on OCN.'"
You: "I said this is IN Europe (ie. The article only applies to EUROPE), it's implied that it doesn't affect Americans. And it doesn't affect many people here on OCN, which is predominantly an American forum."
I'm not denying that there are more Americans here, however, you're still wrong. If you wanted to convey the point you're trying to make now, you should have said, "This is in Europe and probably affects very few people on OCN." By using 'which,' you're making Europe the subject of the sentence.
The fact that it's in Europe isn't what makes it affect very few people on OCN.
