Completely hiding a post.

I have just browsed through a bunch of category-excluder plugins, which all seem to hide a post from the frontpage. However when I click “next” the supposedly hidden post appears. I want to do posts that are only accessible through a link. For instance, for sending something to someone, I can just include the stuff I want in a linked post, and the person can browse the blog, if they want additional information.

I do not want this post on the frontpage, in search, on blog or internet, and not in “next/previous”.

Does anyone know a plugin that does this? 🙂

Peace Be With You.
