A lot of effort is put in by posters on this board as to the notion of proving a claim.
I submit that this is a complete waste of time; there is no need to prove anything.
It's enough to simply make the claim, and then describe the basis for it.
Demanding that tax returns or other records be produced is, frankly, lame.
This is a message board, not a court of law.
Take a man at his word or not; your choice, after weighing and sifting through what is posted.
Some claims, such as Singer being well over a million ahead from VP, or alan's claim of 18 yo's in a row are so patently absurd, so blatantly false, as to be summarily dismissed out of hand by anyone with the ability to ponder, cogitate and judge.
