Hay, Ken, what's ndn? My 1st thought was nonvisual development.org, but then I can't figure out what the last n is. & if it's a lame question, please forgive--it's after midnight & I've been up since early this mornin watchin my daughter have her 1st baby, & I am completely & totally zapped. When u answer, I'll probly go, yeah, duh! but right now I just don't know.
