Some comments are missing. This is because some prat has discovered a url that could be submitted to the site that deleted comments, but only comments.

I have to thank that the said prat for bringing my attention to a bug in the site. The bug is now patched. A more serious fix will be provided in due course.

To those who have submitted comments only to see them disappear into the ether, I can only apologise. The comments still exist in backups and I will drag them out and put them back up onto the site as soon as I write a little script to do so.
