I've installed this but I noticed 2 things. First, if I click on on it does nothing but take me to the printfriendly.com page where I still need to enter the url. I doubt it is suppose to do this.
Secondly, I thought I could pick and choose the pages I wanted it on but it seems it's on all. Is it suppose to work that way?
BTW, I am running this on WPMU. Well, I've deactivated it for now.
