We are working with Jeremy Ruston to move the AMBIT manuals. In doing this, I believe that Jeremy's work will also result in a 'child-of-TS' for more general use. Details not yet clear. Unlikely to be a simple transfer option by the time the current server shuts.
The AMBIT manuals are used by over 150 teams across the UK, and USA, Europe and Australia, so they have become a valuable resource. We are very grateful to BT for the years of hosting TS which we have benefited from.
