All Ebay auction information on EB has been added at the hands of users and a good portion by users who are EB Team members.
If you note an auction that isn't being tracked (if it's still pending) or recorded (if the auction is over), then any EB user can submit the Ebay listing. Just find the print that's being sold and head to the "For Sale or Trade" page for that listing. At the bottom is a box to add in the action # from Ebay - then submit it. All entries by non-Team members have to be verified by one of the volunteer staff here (just for verification) and then they'll be tracked and recorded.
If you're not part of a sale (as in a sale between two traders, not on Ebay), you can submit a sale BUT it's best if you're either the buyer or seller - you can do this thru steps on your own For Sale or Trade account page. if you're not part of the sale, it's a bit "trickier" since you weren't actually part of the deal and any sales are a sort of hearsay.
