Note sure more than 3 works will be picked up (your vormgevers link is broken too). The original post says: "Can I submit multiple things?

For free works, we ask that you only select one item to contribute. If you’re contributing paid works then please submit no more than 3 items.
We think it’s more important that we get as many different people involved and visible as possible than flooding the bundle with projects from more prolific creators, thanks for understanding."
