Many apologies to all those who have been trying to send in responses to my latest blog Top-Down or Bottom-Up? A bug in the computer software was blocking the system. It’s now been fixed – so I will look forward to reading your contributions. Huge thank-yous to all those who add their comments – they are very much appreciated. If you haven’t contributed before, but would like to, just scroll down to the bottom of the blog where you will find a “Leave a Comment” box.
