I'm a bit confused. I've installed it, logged out and went to a page where guests aren't allowed to go. The only thing I see are the first 2 images as examples, but nothing like the third one. Nor can I see within your instructions to alter the custom message, as the "Guest Redirect System Lite" options only gives re-direct options rather than altering messages or code.

Even without the plugin, altering the message you get at the guest access denied page can easily be altered via the language phrases.

*EDIT:
I see what this plugin is about. Re-directing from and or using specific features. But it still doesn't explain how to alter the text. Would be great to share the info to the third screenshot to re-direct to the register/login page like yours.
