You've been given the answer.
See in particular Helinutt's reply. I can't see how he could have made it clearer or simpler.
I find it amazing that you are a helicopter pilot (presumably) and you own your own helicopter, and you didn't know whether you could carry non fare paying passengers in a helicopter with a Private category CofA.
By all means post a question to a flying magazine, but it might be a lot simpler to ask the people who maintain your helicopter.
You did say you had a helicopter, didn't you.
