The NSX Owners Club and the Forum are seperate entities, there was a decision to seperate last year, previously the Owners club had used the forum as the sole means of communicating events etc.
There are still a few of the "old guard " here - various meets and events, like the one coming up at Knebworth in a couple of weeks where Britlude and I will be.
The forum is still the best place for real technical information, FB has a selection of groups.
The NSX Owners Club also has its own website and FB group.
