it seems a troll has found this site and chosen to attack with multiple comments advertising a product to "treat cancer". i won't help him out (it is a "him", i also got an email) by even naming the product here. but his slimy actions have forced me to begin to moderate comments.
which means, my dear friends, that your most welcome comments won't appear immediately when you post them. they will come to me first for approval. i do check this blog nearly constantly for comments, so yours shouldn't have to wait in the queue too long before it is published.
thanks for understanding. and may a pox befall the troll.
