A couple of things...
1. Forum is now a registered user section only as an experiment. Why? Because of the problems that pro/against PLC posters have produced. If you want to post registering brings advantages as you can change permanently the way the forums display and we allow you to use the forums without a visible email address, only one is required for registration, that address is never published.
2. The regulars who have followed things, please do not descend to petty threads and taunting, yes query the facts of posts, or help people but stop the school playground stuff.
