Voting for the location of the CIS-2107 tournament.

Do you sense a contradiction in your statement? The organizer is not financially prepared. Then, how can he even BE an organizer?
This is already beyond the pale....)))

No, I don't see it. The organizer is not the sponsor of the event, but its coordinator. Ideally, the balance for the organizer should be zero – how much he collects from the players, that's how much he spends. Of course, the ideal is unattainable, but still.

In particular, regarding the prepayment – if the organizer is willing to make it from his own funds, that's good, but if not, he can quite collect a prepayment from the players. In the second case, there is more hassle, but the requirements for his own capital are lower.
