A bit of an apology…
…I’ve been a little busy lately, and you may have noticed the absence of many new posts.
More regrettably, though, is that there seem to be a large number of comments accumulating in the pending-comment-moderation queue, and they haven’t been posted.
So, if you’ve been trying to post comments without success, this is why, and I will make sure they’re all posted now. (Unless there are any I really insist on moderating, but that’s unlikely.) I will have to try experimenting with the WordPress settings regarding spam filtering and automatic comment approval a little bit.
