Like many people I like to give back and it makes me feel good. One of the things I noticed recently was that smile.amazon.com now let's you choose the charity you support. Originally it didn't and since I was an early smile user, I didn't notice when the change was made. Anyway, a shout out to Bob Dixon and his son Collins' charity, Bend Your Knees, Inc., which provides support to children with brain tumors and support for research of childhood brain tumors. Many of you may remember Bob from his great efforts on behalf of SEPUG.
