Private until you publish
Collections start private so you can assemble one before anyone sees it. Unlisted shares it by link without putting it in discovery; public lists it on Prototir.
A collection is a curated page that gathers prototypes under your own identity: a course showcase, a studio portfolio, a festival selection. It has no deadline and no winner, unlike a jam. You choose what belongs, in what order, with a note on each.
Collections start private so you can assemble one before anyone sees it. Unlisted shares it by link without putting it in discovery; public lists it on Prototir.
Collected work keeps its own page, author, comments and analytics. You can gather prototypes that are not yours, and the credit stays with whoever made them.
A private prototype in a public collection stays invisible to anyone who could not already open it. Curating cannot widen who sees a piece of work.
Removing a collection removes the page only. Every prototype it gathered stays where it is, untouched.
An organization can use collections for anything: a single assignment, a whole course, a selection of its best work.

Upload a banner of at least 2400 by 900, plus a square mark. Prototir generates three fixed sizes from it and serves whichever fits the screen, so keep anything that matters within the middle 70 percent across and 50 percent down. The editor previews all three shapes with that safe area drawn on, so you can see what survives before saving.
Do not put your title in the image. The page draws it as real text over the art, which stays legible at every size and is readable by search engines and screen readers. The square mark covers the places the banner is not shown at all.
Jams and challenges take the same two pieces of art, at the same sizes, through the same editor, so this is worth learning once.
