I asked a while back about donating my breast milk and if anyone has done it. This weekend I donated 82 oz to a baby who was born with some complications (he was born without a butt hole and no one noticed until he was 3 days old, putting him in critical condition). I found a local facebook page for Human Milk 4 Human Babies which is a mommy-to-mommy donation. I decided not to go through a milk bank, mostly for convenience.
If you're interested I posted about it in my blog - link below, a few posts down.
