…cancer. Which absolutely sucks; I only know him online, but he’s a good guy and I’ve stubbornly kept up with his comic. I hope and pray he gets better.
PS: He also has a PayPal account (if that link doesn’t work, there’s a donation button on his sidebar). I just cleaned out the dregs of mine to send his way; if you were planning to give me anything in the near future, I would take it as a personal favor if you just sent it his way instead.
