How do you code & hide?

[Tito]

I now how to code, but how do you hide your post from non-registered guest's. Example:http://www.divshare.com I want it to be only seen by registered users. You know what I'm talking about. It comes up as "This text can only be seen by registered users" if your not registered. Thanks

Currently this ***rd isn't configured to allow only registered users to read it. There's no way for the user to do this.
