PPRuNe Didn't Do Anything Wrong
Dear ET,
To ensure that there is no misunderstanding (and that we do not offend our kind hosts and moderators who provide and maintain this valuable forum), I said that I looked through the thread to test the above theories, and came up empty. PPRuNe has not deleted references to Sheikh Hamed - which was one of my guesses, only, and proved to be unfounded.
It could also have been a cleansing of duplicate postings which existed in more than one of the merged threads.
I just don't want my wild guess to be mistakenly attributed to PPRuNe. That might start a rumour, you know.
