Quick suggestion re the interface for the forum.
When looking through the boards, there's a link, on every post, that “looks” like it ought to take you to the most recent post in that particular thread; "See Most Recent". Very useful... except that it doesn't.
Instead, it just goes to the latest poster's profile page; not much use really.
How about making that link actually work, and send you to the thread's most recent post?
Every post within the thread has a “see most recent” link, so a simple fix, that would make navigating posts much easier.
e.g.
Over promise, then under deliver = negative buyer experience, INR cases, unhappy buyers and sellers.
Under promise, then over deliver = Positive buyer experience, joy and happiness all round.
If only eBay could get their heads round this basic concept, this would be a happier place for all.
