” the definatiin of Rav is also somewhat loose, They just make some sort of flyer and pass it in along in Israel and the US and get a few in Europe (Most of the signers are from the US or Israel)”
I don’t think it’s so simple – I know someone who was once asked asked to be the 100th Rav (or maybe it was the 99th). He was asked to be the 100th (as opposed to 1-99) because he is not a Gadol, but at the same time, he is a Talmid Chacham and Posek, and he was specifically chosen because of that – it wasn’t just passed around.
