Thanks to the abuse of the anonymous option for leaving comments yesterday, I have had to make a change here. For the time being, nobody will be able to leave anonymous comments.
The vast majority of people who do leave anonymous comments are able to do so without resorting to calling anyone names, and even include their name on their comment... just as I'm sure that the vast majority of this blog's readers are reasonable people.
And sometimes it just takes one unreasonable person to cause a problem.
I'm sorry I had to resort to this option... if there was a way to just set comments so that anonymous comments had to be approved, I'd go with that.
