You'll need to override the profile/listing view, but only when Elgg is rendering your plugin's pages, not to interfere with other plugins that might want to use the core profile/listing view.
Please check if "Use view filepath cache (recommended)", is disabled in the site administration. Because elgg uses hard view cache. Or delete the view_cache file from the data directory.
And also make user your plugin is below the "Profile" in the plugin list.
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.
