How do log your penguin in Club Penguin?

When you go on to club penguin it should say play now
Press that then it should say play. if there is not a penguin saved the log-in screen will come up if there is a penguin saved at the bottom it says log in as different penguin you press that and log in screen comes up.
When you have done that it will load and tell you what server to go on
you can chose whatever u want the more green bars the more people if it says full u cant go in
if there is a smiley face (yellow) it means a buddy is on line that server
