Well, I think I recall Denise mentioning something about her and Jason taking a brief vacation, but it wouldn't be for Thanksgiving, because they're from Canada and have a different celebration. And Russ is British, so he's definitely still around. Mostly we're just busy; I've seen Russ post a thing or two in the past few days.
If it's urgent, don't hesitate to post a notice here asking Russ to look for your message. He receives a heckuva lot of emails each day, so I wouldn't be surprised if he hasn't replied to them all.
