If any thread became a regular posting place (which is highly unlikely) can you imagine how stressful it would be having to scroll all the way down to find the last post each time. Its bad enough doing it with 7 replies.

Is there no-one to appeal to about changing it back?

Ive noticed theres barely anyone replying to the qu's on buying and selling boards. Half the people ask something, and youve no idea if theyve found their way back to read the answers if they dont reply. 

I expect if eBay staff were having to use this system to sort out everyone's issues themselves, they'd be demanding a payrise 😦
