I recently re-joined mumsnet as I have a very small Facebook page of just a few family members and friends. I don't do Twitter but I do help a closed specialist Facebook page and website. In the 5 years I have been a member I have only had one hurtful comment regarding my opinion. On two threads I have posted on mumsnet I have been called a liar. Why? I wouldn't dream of making such a comment. Perhaps I am naïve and should not let it bother me. Naturally I have had some excellent advice which was what I was searching for outside my own sphere of contacts. Just me?
