I've enabled comment moderation as I've received a "SPAM" comment (I mean a genuine, gibberish SPAM, not simply a comment I didn't like).
I've had moderation off on the basis that free commenting enables conversation and under the apparently mistaken notion that, as 'owner' of this board, I had the ability to remove comments.
For some reason, some of my posts seem to allow me to remove comments and others do not. So I will leave moderation on for awhile and see what happens. Apologies to those who comment here.
