I have a little compused when I found account cooper member,

What is the difference between cooper membership and a regular account?

Is there a privilege when the account has the name cooper member?

I found a lot in https://bitcointalk.org/index.php?board=238.0 accounts that have cooper members always have a lot of participant if they become a bounty manager even though the account is still a newbie, and different when a newbie without cooper member account less desirable by bounty hunters if they become a bounty manager.

Sorry for the stupidity that I have with this question, or alternatively someone can provide a link for me to read about the difference between a copper member account and a regular account.
