I think the "test" or qualification idea is a good one in theory, unfortunately the whole industry at moment is being mismanaged and we were only talking about this the other day. Ethics, codes and even the ideas of giving from the highest is being replaced by many (not all) it is tough to separate the good from the bad, but then guess that has been a problem since time began.
I suppose as a psychic an individual can answer to themselves and who and what they believe in, and as the believer we can only trust our own intuitions and what we have to guide us.
Shame on the psychic phone companies which see a "reader" as a number and a "caller" as a cash sum. Their downfall will come we hope
