A quick note and an apology: I've had to modify the site configuration to require users to be registered and logged in before they can comment. We've been taking a ridiculous amount of comment spam, and it's consuming more and more time to weed through it.
You can register using any major social media account, so you don't have to remember yet another username and password with us, so hopefully that'll mitigate the inconvenience.
Have a great week!
