Apologies...

... to those who have left comments to our posts on here in the past, and to those who may have done so in the near future. As some may have noticed, we have had a spate of adverts posted masquerading as "comments"; and it was getting to the stage at which we felt it was adversely affecting the quality of the site. The comments feature has been disabled while we look for a better solution; we hope to have it activated again as soon as possible.
