Okay, urgent measures called for.
Sorry folks but certainly for the next couple of weeks I'm restricting comments to registered users of Blogger. Am REALLY sorry to those of you who aren't users of blogspot (well, mostly) that you won't be able to comment for that period but needs must. I got seriously spammed and I don't want to check in on a full inbox of spam comments whilst I am away. I've left a sample of the way they're spamming pesudo-messages as "anonymous" but friendly comments to show why I have done this.
Tough love will be reconsidered when I have more regular net access to monitor things.
