With this there is no subscription option that I am seeing. As this is publicly available and does not require you have an account Im not sure how that would work. On the Old support site you could but that does not seem to carry over.
And, isn't sanity really just a one-trick pony anyway? I mean all you get is one trick, rational thinking, but when you're good and crazy, oooh, oooh, oooh, the sky is the limit.
