In my experience, quite a few people associated with NARCAP are actually fairly active participants on some UFO discussion forums and, particularly, several UFO email discussion Lists (both public and private) - including Dick Haines, Martin Shough, V-J Ballester-Olmos, Jacques Vallee and others.
I don't post much on this forum, which is one reason for my lack of participation so far in this thread - but don't mistake my silence (or, probably, the silence of quite a few others that lurk on this forum) as a lack of interest in the work of NARCAP and its associates or your posts here.
(My main reason for refraining from posting in this thread so far is actually that I didn't want to impose on your time by posting various questions and comments).
A lot of NARCAP members including myself participate in public forums but we/I don't often do it in our capacity as NARCAP members. Haines, Vallee and many of the others you mention have their own work and research that they promote and dialog about and as far as I know we are all careful to define our discussions as speculation or otherwise outside the NARCAP domain. There is a difference between what any of us suspects and what NARCAP offers as information. The only people that generally represent our work publicly are Dr. Haines and myself. I don't often participate in this forum at all and probably wouldn't be here now except for the interview.
