I can only speak for myself but when I feel a post is something you'd share with a friend, not someone you'd meet on the street I move it to PDA.
details of illnesses or tragic events I feel are not for the general public.
like someone said we are volunteers and try to do things the way admin. wants it done, he's the one who chose us, (even tho he's not here anymore)
if you have a problem with a topic moving or deletion or whatever you can discuss it with the one who moved it and find out why or plead your case or whatever, it's not carved in stone and can be changed,
we're not trying to throw our weight(buttons) around. ;)
