Below, with a new FAQ, the new log in system from Monday...
Our technical people have sent us this:
"We hope that the new system we are using (called 'DNA') will be much more stable than the old one, as it has already proved to be reliable in handling all the traffic from the BBC's message boards like the Archers and communities such as 606. This is the first time we've tried it on the blogs though, so if there are any teething problems please bear with us.
The new system has some differences, the main ones being that you will have to register with the BBC's Single Sign On system before you can post, and that the comments will be ordered with the latest comments at the top."
