The "Know" toy is a little free dropin that can be placed on any page to add a little ever-changing variety (it comes up different every time)--it places a question of the form "What do you know about xxxxx?", where xxxx changes randomly over almost a million topics, and is a link to an online encyclopedia page on that topic. That dropin requires upgrading, owing to a fairly major change in pagename formats on the encyclopedia it calls. One need only drop the new one in over the old, but the old will no longer work as expected. This is the download page .
