Is there a plugin or a way to block all of a blog except for a single page or post i allow. This could be any page within the blog, possibly allowed through adding a string to the end of a URL or something???
For example i wish to send out a newsletter and allow people to access the single posts i link to in it. However to read the rest of the blog they must first register with us.
Kind of like Quora allows you to see some of the content but you must register to see the rest.
if this doesn't exist is it an easy task to do?
I know there are plugins that require a visitor to login to access 'set' pages, but i don't want to set pages, just to allow access to the single page i link to and not the rest.
