On Mumsnet?
Chatting about MN - colleague is an avid user - and I said I love the function that allows you to change names when posting but on threads your on it will revert back to the name you used originally for that thread.
Colleague has always used same name, it turns out but I have used lots! To keep anonymous.
Colleague loves to try to find RL people on MN and has now said is determined to find me, and all my user names! Said had tried before but never quite pinned me down!
AIBU colleague has proved my point!
