Currently in Club Penguin, everyone is displaying as a member – even non-members. However, unfortunately, non-members still do not have access to member features.
This glitch was also brought to my attention at the Club Penguin CP Halloween Party. As you know, there was a Halloween Costume Contest – there would be three winners; two non-members and one member. However, everyone displayed as a member so there was no telling if the penguin was really a non-member. Thanks Hermey1 for telling me about this glitch.
