OK, I installed Nuke and tried the Google Tap integration. I did a quick once over on it and found that it was not functioning. I did a quick look on the web and found that there were several people having issues getting it to work properly. I did find an article at NukeCops for it though at http://nukecops.com/PHP-Nuke_make-php-nuke...e-friendly.html. I did not have the time to follow through to be sure it would work.
You may want to try sitemapper or GT-NextGEn.
