First off we NEED to know WHO, WHAT, WHERE, AND WHEN. SO far it appears we only know who. So you really need to clear this up before you post anything else.
I would assume you want Chaim to give a talk where those who attend pay at least $50 to enter (all money goes to JTF after expenses). I assume it will be in a hall of some sort in the NYC area and will take place right before or right after the High Holidays. Again I am only making assumptions because few specifics were given by the thread originator.
