I actually haven't tested it heh
The site I currently manage, I haven't added it too yet as the email integration stuff is a priority. It's on my todo list.
If you'd like to test it out, rock on
If not, when my list finally works down enough I can take a peek at it, then I will
As long as /clientscript/vbulletin_global.js hasn't had a serious rewrite, there is no reason why this shouldn't be able to work just fine in the newest version
