What is Backpack? It is a web based project planning tool. No gant charts or any difficult projectmanagement-lingo, but plain ol’ lists! In Backpack, you can make several pages on which you can make lists of “things”. You can make a page for a conference you are visiting (like I am next week) and on that page you can make lost of things you need to bring, emails with confirmation from the hotel and train and a map of the area.
