I also share with the entire bicycling community the shock and deep loss we've suffered due to his too-soon passing. Though I never met him, I'm sure I'm not alone in thinking that nevertheless I knew him and feel like I've lost a friend or family member.
I'm sure his family may have a charity or memorial we can contribute to, but I'd like to propose that a fitting tribute might be that we all strive to keep his websites up and updated in perpetuity, so that he continues to help and inspire future generations of cyclists.
I'd like to help with that effort, in any suitable way that I can.
