Mick's hit the nail on the head.
The link to the post is in PieEater's excellent wee "All about the thou" post, aim has always been not to go the way of Yuku and have a million sticky threads and I'm of a "three and out" mentality, we had hit three so I started trimming.
If you want to start a new one in For Sale & Wanted I'll happily pin it there for you.
