So very true that posts can be read by anyone. In fact there was a programme on Adelaide (Australia) television yesterday called the Chat Room. They were talking about a thread on Mumsnet where a woman was invited to a wedding, she gave money as a gift, I think it was a hundred pounds, and was asked by the bride to give more. The reason for asking for more was because the poster had recently inherited money.
The people on the programme at least agreed with the woman who had started the thread and thought the bride was very cheeky.
