You can check the kiosk in-game. Or you could try that link. It ought to take you to your emblem collection. If there's an easier way to get there, other than bookmarking, anyone's welcome to let me know. But the path I travel is: My Legend (upper left of the page) --> Vendors --> Select Tower (center, top) --> Select Emblem Collection (bottom left).

Its in one of the collections near the shader collection.
