How do you change your chat mode on club penguin?

If you are talking about how to change chat mode on a server, it is impossible to change it unless you log off then log back on and go to a different server.

If you are talking about when you made your Club Penguin account and you

picked Ultimate Safe Chat, some people would say to use a Parent Account but I'm

not sure if it works. You should ask on this website how to get your parents to

make a Parent Account.
