How to make pages visable to Non Members

[netanya]

Hello
Just new to downloading this plugin to my site...My site is a classified ads site that I want to be free to browse all pages, except the placing of a classified ad. How do I make all pages visable to anyone, but only restrict one page please?
When I installed and activated the plugin, it restricted all pages until member logged/registered in which is not my aim.
Hope someone can pls guide me. Thanks
