Membership on Emerald Activities is free for everyone. It includes a personal gallery to store your creations, the ability to create an avatar and make assets, and of course the chance to earn emeralds and unlock new pieces!
This is a maker that lets you use assets you make in the other Magic Makers to create your own dressup game. (The kind were you click the arrows to change the clothes.) It is still in the very early testing phase, so not everything works. But if you want to know a little more then click here. You can view example dress ups on the Dress Ups page. You need to be a member for this one since it needs assets to work ;)
