It seems quite a few readers have been having problems leaving comments on this blog. And, indeed, I have problems replying to those of you who have fought your way through the system.

My apologies to you all. Basically, in an attempt to stop spam, Mike and Steve, who wrote the code for the Knotes system, seem to have tightened it up so much it stops almost everything. Mike is hoping to sort it in the next couple of weeks. In the meantime, if you do have anything to say, please email me and I will post it as a new entry. Even if you disagree with me, I promise.
