I think this is a bug, as discussed in the other thread. URL1 Mahalo is beta, and often has very strange bugs. Things that you added not showing up or moving around on their own is recurrent problem that's on the bug list.
But all of the content on an entire page disappearing is a new one!
There was a recent complaint from another fellow Mahaloian that her page contents have disappeared overnight. I think you should better take a look at this. mahalo.com/answers/mahalo2/other-people-... I only know that Brown Belts & UP can edit others pages.
You should try contacting @jeffhoard to solve your problem. :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
