I’ve noticed that if you just try to go to thinkatheist.com, you get redirected. But a link to a spot inside T|A seems to work for me. Then one can navigate around.

From there you should be able to navigate to unseen’s discussion, assuming that link works for you. If it does, leave that tab open (if you can).
