I hope it isn't bad form to speak for Danny here, but I've had a few different folks asking me about him and it's easier to reply here than fire off a bunch of PMs.
I talked to Danny about a day ago. There was an issue that came up during the surgery that extended his hospital stay and put him in the ICU. When I heard from him however, he was feeling much better (and in a well-enough state to calm down my worries!) and he is home now.
He plans to be back online later today. Here's hoping his typing skills are up to snuff!
