I'm currently creating a new theme for my blog and I intend to make it in a magazine style manner.
So, to clarify the question in the title: what I want to do is to create a text assigned to the post, but not displayed in the post itself. Lets say that the user Tom writes a review of the movie Black Swan - what I want to be able to do is summarize that review in a sentence or two - and use that text as an "excerpt" on the front page.
Any ideas? It's probably a lot harder than I think it is.
