What is the active window?

The active window is the stretch of time around a show when its spotting-and-sharing features are live — not just the single show day.

It opens about two weeks before the show starts and stays open until a few days after it ends. During that window the show is Active, so registered attendees can share wantlist items and spot each other's finds.

Why a window, not just the day?

Collectors plan ahead and follow up afterward — lining up wants beforehand and recording finds for a few days after. The window gives breathing room on both ends.
