To make sharing posts with users that do not have a WordPress login easier, we have setup the Public Post Preview plugin. This allows you to share a special link with users, who can then view a post without a login for up to 48 hours.
Sharing Post Previews
To share a post preview, got to the edit screen of any news article, page or Giving Story. From there, you will see an "Enable public preview" checkbox in the "Publish" metabox in the top right corner of the admin. Copy and paste the URL below this, and then check the "Enable Public Preview" box. This URL can then be shared with guest users.
URLs will be available to users for 48 hours after which time, for security reasons, a new URL will be generated.
Note: Post previews will only be available for posts that have not yet been published.
