I should make one small note.
If 3 or 4 people bring up the restored NODS during the chat, that's perfect!
Any more and it would seem suspicious...especially since the participants will have answered the first inquiry, and want this not to seem like a campaign or plot.
My suggestion is, that if you see someone has asked about it while waiting for your turn, ask about a different title, say HODS or whatever old Warner or MGM title interests you, but note your interest within the question.
For example, "Let me say that I'd also love to see the restored version of NIGHT OF DARK SHADOWS on DVD, but I was wondering if there were any plans to put any of the Val Lewton films on DVD?"
There's tons of films in the MGM catalog, including the classic musicals, all the RKO titles, THE MAGNIFICENT AMBERSONS, GREED, Greta Garbo titles, etc. that have yet to be announced for DVD release.
Remember, the more polite, courteous and professional the question, the more likely the particpants are going to answer it, and the more serious they'll take the request.
Good luck!
