I found those directions unclear also (though they got me pointed in the right general direction, so thanks for that). For anyone else wanting to know:
1. Once you install tampermonkey, click on the icon at the top and select "go to dashboard". Then select the "Utilities" tab.
2. Follow the [url="http://zack.st/Userscripts"]"zack" link[/url] others have posted, right-click on BOB link and choose "copy link address". (Or copy this one, working at least for now:
http://privat.bahnhof.se/wb993794//User ... OB.user.js )
3. Go back to the tampermonkey tab (still under the "Utilities" tab within the tampermonkey page), and the bottom option allows you to import from a URL. Paste your BOB link in there and click "import", then choose "install".
Then the rest works for me just like BOB always has. Hope this helps!
