Commenting is FUBARed at the moment. I'm trying to restore it, but Disqus isn't cooperating at the moment. I'll let you know as soon as it's fixed. My apologies.
UPDATE 1: And now my Tree of Life template got fucked trying to get rid of the commenting glitch, so we're back to pie. Comments still broken. Disqus support still not responding.
UPDATE 2: Well, I'm pretty well stuck until Disqus decides to respond to requests for help, so, in the meantime, I'm just going to keep posting, but please be advised that any comments left at the moment might be lost later. I will let you know when normal commenting is restored.
UPDATE 3: I think comments are in working order again. Apologies for the inconvenience, and my thanks to Ryan at Disqus who explained how to resolve it.
