PS Chris, the T-shirt (or maybe a coffee mug) is on the way just as soon as I can figure out how to access the funds at PayPal. If you want the shirt, I'll need to know which size. If you want the mug, I'll need to know if you need a top vent AND a drain connection. This is most likely "post of the year". Thanks.
