500N in answer to your question.
"Mrs Bloggs 'At Home' Etiquette/Protocols" it was NOT deleted as you wrongly assume. It received its last post on 6th Jan 2011. After that, when all the steam has dissipated, it left the forum and now lies 'asleep' many pages down in the abyss of PPRuNe's archives. That can happen even after ONE day on the front page. Such is the turnover of threads in making way for others.
