Do you know where your toolbar is? It's the bar that has stuff for you so you can talk. There, I think next to the snowball icon, is a little picture of an igloo. Click on it, and you will get to it. For membership, you can buy stuff for your igloo. If you don't buy membership, you can only by one red puffle and one blue puffle, or two red puffles, or two blue puffles.
