A few weeks ago we had another discussion of Hidden Doors. The
discussion focused on where to get information and the results
individuals have had. It did not have any summaries from those
who researched the topic at that time or remarks by those who
have tried or compared multiple solutions. Without repeating
what we have already posted, could those who can expound, from
first on experience, on the different methods, reply with their
knowledge for the benefit of the rest of us?
