Freecycle

I was talking with a friend of mine today and she mentioned that she wanted to dispose of an old computer. 

Of course the problem is you can't just throw out the old machine.  A great resource is Freecycle.

It is the 2008 version of 'putting it out on the curb'

You start by searching for your local area and then registering. You can then post that you have a computer to give away. In most cases you will have several willing people within a day. 

You are helping someone out and reducing waste!
