Interesting question.
I knew the late Fr. Frederick Schell, who advised strongly against using the Internet. He was old school in that way, and believed in using pen and paper if not just picking up the telephone.
Now I wonder if there were any priests who grew up without telephones in the house who counseled against their use!
In any event, the answer is "no." Fr. Poncelet takes his crusade against TV all the way to the use of computers. He is absolute in his denouncement of every kind of visual electronic display. He has written two books on this topic, Air Waves From Hell, and TV: Prelude to Chaos. You might know about them.
Therefore, he has no website. He has no e-mail address. But if you would like his mailing address, I'll look it up for you.
Fr. Schell is a ledgend. My own late pastor, Fr. Paul Wickens, learned a great deal from Fr. Schell about the establishment of Traditional chapels. We had a detailed discussion of his experience in CA.
