cookie.txt? | Freeware Plugins | CyberSEO support forum

In the installation email is this line: You must make cookie.txt writable for the script (chmod 666). Otherwise the plugin will not work.

I don't understand what that means. Where would I find said cooke.tx and how do I make it writable? I unzipped the plugin and see it in my control panel. Getting ready to fill in the fields and get it set up. Before I can use it and have it work I need to make this cookie.txt writable? sorry, hope that makes sense but my understanding of wp is on a basic level :)
