I was just reading a post and it reminded me of when i was first on mumsnet and made a few blunders, the first posting in AIBU when i was a newbee 
Although i never admitted it to any one then my next blunder in my confusion of many acronyms one was thinking that TIA was actually someone signing their post with their name any who for any newbees out there who are in their first days of mumsnet this thread will make you see you are not alone, and also some what cleverer then cookielove 
Come wise mumnetters share your blunders, your blushes and your mis understandings here
