I was actually trying to take a look at #CalcKey and see if it might be worth migrating over there, but other than a brief blink of what I presume was the site logo, I was basically getting a blank screen. I'm guessing, with the context of your post, that the server was getting hammered at that point?
I'm not in a tremendous hurry to migrate my account, but I'm keeping my mind open to the prospect. I'd hate to lose my "history" here, though.
