Is it possible to dynamically modify role permissions and also generate the appropriate sitemap/menus in ASP.NET?

Yes, it's possible to do what you're saying. You can dynamically create the sitemaps using a custom SiteMapProvider, see this articlet http://www.codeproject.com/KB/aspnet/dynamicsitemap.aspx .

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.
