Of course, original UAE hack can't be applied for guest because the hack needs a profile (a registered user) to save the agreement!
Infact UAE hack was only appliable to newthread.php, and so in standard setup only registered user could create new thread (and so use rules hack).
This addon only put a little modification to the hack: now is possible to extend rules visualization also on the whole forum.
What appened? Now you need to pay attention and use it only with forum available for registered user!

mmh..So you would like to don't save agreement in case of guest user.
Ok, I'll work on it!
Wait for next version!
