This is how I load it at the moment. http://www.smalltalkhub.com/#!/~philippeback/HOWebStack
It would be great to have TwitterBoostrap on smalltalkhub as well as it still lives on SS3. In 3.0 the status/ app is broken. 3.1 fixes it but I've but my own things in there. It works with one app, albeit I do have some issues I'll look after tomorrow morning as I am developing a new application based on that codebase. Phil
