Can I keep merging repeatedly from a branch to trunk with Subversion merge tracking?

Yes, this is exactly what it is designed for. Since the svn:mergeinfo property on trunk is keeping track of which fixes from 1.0 have been merged back, running the merge a second time will not result in it grabbing those revisions again.

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.
