The person who posts it sends you a collection invite thing, I've been entering your name it wont take.
Feel free to upload it yourself, their collection thing wont work, I've even copy pasted your screen name there.
That's what I'll do. Just upload it. It's what I usually do with something I've commiished anyway. I think the collection thing was a bad idea in the first place, from what I've heard of how they intended it to be used.
