Discussion with NAV has been suspended due to legal action towards HC.
But since NAV went into administration, Madmin posted the following just before "Beta" went live:
Of interest, one of the companies that spent theirs, or their directors funds legally chasing discussion of their Company off HotCopper has recently gone into administration.
That is NAV - Navigator.
We will therefore put that code back for discussion on the new HotCopper so shareholders can discuss their options.Source
So if you like to discuss your options, it is available on the Beta Nav forum, which can be found HERE
