And what about users who visit your site without a mouse? Try it. Navigate through the menu just using your keyboard’s TAB key and see if you can get to any of the Contact sub-pages.
I didn’t think that was a big concern. Do you have a plugin you can recommend?
BTW: if you stumble across this post, download the plugin Page Links.
After installing, go to the page you want to remove the link from, and in the custom fields, create a custom filed called links_to and give it a value of “#”.
