From the editors:

Our comment feature is fully functional again.  Feel free to comment.  The comments are moderated, though.

Our ‘spam-filter’ had gone on strike, for the last two days and at one time, we had 18,500 comments, mostly spam of course, to moderate.

Consequently we had a little problem to approve your comments.

Now we are back in business.

Thanks for understanding and sorry for the trouble.
