The site does say :- "This on-line memorial is in the early stages of construction. My aim is to complete it by the 100th Anniversary of the battle - 20 November 2017 - to honour those who served in the tank units which fought in this historic action. It is a mammoth task as about 3,200 men went into action that day. Please help me build it as a fitting memorial to their bravery" So I guess it's a work in progress.
