The short answer ...No ...
We receive very often this question. Our success lies in the small and mobile team we are, where participants have an exeptional confidence with each other. It is also associated with the resource people we work with. Our vision is - at any time - to appear professional, and - for all the world - not do what "everyone else does on TV."
Witnesses safety and rights rather than the YouTube popularityWe will protect the witnesses as best we can, and therefore we choose not to accept any new members. Witnesses often tell about very personal things and experiences. It would be a disaster, if such information went public.
The risk is that a stranger joins the team, just for "kicks". We also assess that enthusiasm so may end up in a YouTube video that is not in our or in the witness control. However, we gladly refer to the "stupidities", that we make ourselves, as long they are anonymous. It belongs to job satisfaction!
We choose to work together with the resource persons, we find interesting. For instance clairvoyants, where all our science does not fit anymore. Or scientific professionals, where our knowledge is insufficient.
