Tnx, all.  I had been a lurker for sometime.
This is a really cool site.  I just noticed this morning that when I click on a new screen, the old screen just slides slowly off to the left.  Cool.
Originally, I had only watched about a month or so of DS back in the fall of 1967 when I was freshman in college, so I was just familiar with the 1795 sequence.  
I rediscovered DS on the SF channel last December, subsequently  borrowed tapes from a friend of a friend, so I've now seen about 80 per cent of the episodes.   I'm looking forward to seeing them all - then,  no doubt, starting over again.
I chose JoeNathan mainly because, if given a choice, I would like to LOOK like JC, though he was a really good actor too.
