northnorthwest - you are playing the victim card. Your very first post to mumsnet - your first post ever to this whole site - started like this:
"I have just joined Mumsnet but I am really shocked at the nastiness of some of you - who probably pride themselves on being nice mothers."
This is not a good way to introduce yourself to a community - and it's not surprising people were not terribly 'nice' to you.
You went on to say:
"The people saying horrible things like "knob" are really unpleasant and you give this website a bad name. I hope the other people on this site aren't as stupid. If they are I won't be a Mumsnet member for very long."
Why on earth would you expect people to be welcoming to you after that? 'Unpleasant'? 'Stupid'?
It's like joining any conversation or party or meeting - you don't jump in and tell people you have never spoken to before that they are nasty and you don't like their language and that you hope others there are not as stupid....
Sheesh.
