The copper membership allows those users to have an avatar. It should be a feature who come with the rising price of that membership. 0.0065 BTC isn't a bad price at all, but maybe the CM thread should be updated because it doesn't mention the Avatar.
I highly doubt this is true, we would already be seeing dozens of Newbies carrying those avatars and with such a change even though it seems minor, Theymos couldn't have forgotten to include this information alongside the price change announcement... but then again I could be wrong.
You're not wrong, He just didn't bother to read previous responses. I already said it's like not a new feature, I could tell since I'm Copper Member privileged and I'm sure one of those users didn't just pay for CM recently.
