What can I do to prevent the user from going back to the index page if they wanted to comment on an article they found several layers down from the index page?
Example, visitor goes to Home --> World --> Asia --> My first Article.
If the visitor wanted to comment on "My First Article", they would need to login, but then they are taken to the "HOME" page, not the "My First Article" page. This means, they have to search again for the article to make a comment. This is too complicated.
