钱是你们的钱. Who cares how you spend it? Don't ask people to sign it. It is just trouble.
We have a trust fund, contributed by all the classmates in US and Europe, annoymously. The goal is to help whoever classmate that has financial hardship. It is on the "needed base".
One we heard the bad news, we have a chat. Then at least 2 people will pay a visit. Money is distributed right on the spot. No signature. They can spend whatever they want.
The rest contributions is sitting in several funds and gaining interest and dividends.
