I’ve tried to simplify the system for commenting on this  blog. Previously, readers have had to register as users to comment, now anyone can comment as long as they provide a name and email address. However, your first comment is still held in a queue for approval. Please be patient- I’ll almost always get your comments up within 24 hours (right away where possible) unless I’m stuck on an airplane or lost in the forests of wherever.
Thanks!KW
