Where I can learn the remote viewing protocols?
Start by learning the difference between a required Remote Viewing Protocol and the assorted psychic methodologies often referred to as "RV Protocols". The first is critical and the basics are always the same. The second is useful but optional and the methods vary.
The way the question is phrased I think you are looking to learn psi methodologies commonly used in RV. There are instructors with varying levels of skill, follow-up, pricing, and so on. If you are interested in the methods you can try Paul Smith at www.rviewer.com, Lyn Buchanan at www.crviewer.com, David Morehouse at www.remviewtech.com, Glenn Wheaton at www.hrvg.org or Pru Calabrese at www.largeruniverse.com. I do not endorse ANY of these sources, I am simply listing a few that I know of.
If you have a hang-up on the concept of Ingo Swann being the source of your ‘methods’ then I suggest contacting Paul Smith, who is probably closest to that form.
