Uhm, I would expect a reply to provide that clarification.

I expect to find useless and inappropriate comments downvoted, but there is no official policy that I remember, so those are only my ideas of how downvoting would help moderate a discussion.

Then the people that downvoted should provide a correction. I still don't know what IC is supposed to stand for. I'm assuming it's not integrated circuit which is what I think about when I see IC.
