The template that OpenNTF uses to manage all the open source projects on the OpenNTF site.
When you submit feature requests or save an item in Project Discussion you get a page with "[]" on it. This is not at all intuitive and it's hard to get back where you were.
Tested using IE 6 on Windows XP. No Popup filter etc installed. It works quite well for casting votes but not when submitting responses to documents or posting releases, tasks, etc.
