I have been thinking for some time that it might be helpful to the board to have some sort of (unofficial) moderator to help some of the problems which several people have highlighted. It is my personal feeling that it might help to have someone to step into some of the threads to stop them going into a downward spiral and maybe calm things down a little.
I don't mean just to report personal attacks but more generally to try and change the atmosphere. I know many people have felt inhibited from posting their views about certain conetntious topics because when people have posted against what is felt to be the "orthodoxy" they have been given a hard time for it. I wonder if it might help to have someone not personally involved and not posting their personal opinion but with the specific task of calming things down and improving the atmosphere and level of debate. It might help to depersonalise it a little.
I think there are many people on this site who have the right level of sensitivity to be able to do this well.
This is just my suggestion and is in answer to the many concerns raised over the past few days/weeks/months about the way mumsnet is changing.
