For the non-cartoonists who want to support Team Cul de Sac, you can choose to contribute money directly online.
The Fox Foundation's website for Team Cul de Sac is somewhat confusing, but click on that link, and then select the big orange button that says DONATE NOW. You can select amounts to be charged to a credit card. If you want to join TCdS, there's another button for that, but there's a $50 fee, and I'm not sure what benefit there is to that.
Mason Mastroianni of B.C. is the latest artist to join.
