Was about to say the same thing, PresidentO, 
Also wanted to give a quick progress report to say we've mailed a number of posters whose comments on the LTB thread had been reported for being disablist (intentionally or unintentionally).
We've also received a couple of mails already in response to our post on that thread from people who've reconsidered their comments and realised that they may have come across the wrong way.
It's small progress, but a step in the right direction and we're going to try to keep posting on threads, keep sending mails out, and keep trying to hammer the message home that we won't tolerate disablist posts on Mumsnet.
Thanks for bearing with us.
