In the last PM I received from chess, he said he had to write up an important paper for his toxicology "day job," which he had been procrastinating as much as he could (yup, he is just like me!!! HAHAHA...). I believe he did mention when the deadline is/was, but don't remember the date. I hope he is in the middle of it right now, and comes back as soon as the task is finished.
