I joined Mumsnet when my first DGC was expected, so must have been 12 years ago. I learned lots about the modern ways of parenting and particularly liked a somewhat subversive, witty, strongly feminist group of posters, who dominated some of the threads.
Eventually this group got fed up with constant attacks from other members - they were accused of being a clique, which I suppose they were, as it was obvious that they talked to each other privately by PM. Suddenly they disappeared from Mumsnet and set up a private group on Facebook. Various other Mumsnetters were invited to join their new group - some did and some did not.
I was not asked and was very disappointed
