Today I found that this domain seems to have been taken over by some other organization. Does anyone know if the NAPCO site still exists? | | | | | Joined: Jun 2001 Posts: 793 Bondo Artiste | | Bondo Artiste Joined: Jun 2001 Posts: 793 | It appears most of the Napco action is on the Facebook now. Google is your friend.

I'm not allowed in because I'm not a Facebook member but my guess is that any old technical info is gone.
All I can see is member's photo albums.

My opinion only. I'm guessing the original site died a natural death because of a lack of participation/members. Unfortunately, some really good technical articles/submissions are lost, probably forever.

He lost his pubs as well. I own a couple NAPCO’s now, but I’m no longer on my all-encompassing quest for knowledge. I’ll help out where I can, but I’ve forgotten a lot of what I picked up over the years. It’s a shame that new NAPCO owners don’t have a reliable source to turn to.
Take care,
