I'm having one hell of a time finding the file in vBulletin that controls the sig links. Anyone know where I can find the file to edit my sig code?
Links in vbulletin signatures are already do=follow by default. If you use Firefox, install this plugin. http://tools.seobook.com/firefox/seo-for-firefox.html You can toggle it on and off at the bottom right of your browser. With it on, no follow links show up in red on a webpage.
