Well, to begin with, you can donate any amount at all. Everyone keeps postponing the idea thinking they would like to contribute something 'significant' when they have it, and the result is these guys miss out on money completely. Even if you give $1 (45 bucks), and 1000 other people think so, they have $1000. Pretty significant amount.
You are quite right, but i was thinking how about we Mint users all pool together, contribute say 50/100/whatever rupees each in a local account, and then send it in the name of IBF users, we won't look so cheap individually then (Yes, the thought of appearing cheap absolutely terrifies me, besides opening a Paypal account for a 100 rupee transaction doesn't seem feasible to me, i don't even have one). Maybe admin would be kind enough to help us out in this.
