Going forward, all comments will need to be approved prior to their posting. You will see a notice to this effect when you click the "Publish" button after you've completed your comment. This change is due to a recent barrage of rude and obnoxious comments from one individual.
The moderation process does cause a delay in comments posting to the blog. The delay should be minimal as I am able to approve comments from my phone. Any comments left after about 10 pm at night will be approved first thing the following morning.
