There appears to be an error with the block after the first post in any thread, where eBay
items from the thread originator are highlighted (assuming the poster has an eBay
userID on file here).
It is captioned "Newly listed items on eBay
by XXXXXX" and presumably what should show beneath it are their newest items. However, when I browse the forum, what it shows me in all instances are items that I am selling (which I obviously don't need to see).
So I think the block display code might be filtering based upon the eBay
userID of the viewer rather than that of the poster.
That would presumably affect clickthroughs.
