GTD in Basecamp

Patrick Rhone has a great post in his blog or journal as he calls it in regards to implementing GTD in Basecamp. To assign contexts he set up people, with context names like @office, @call and so on. He then goes on to assign tasks to people, ie contexts! Brilliant IMHO! Since Basecamp is free when you have just one project and it’s free to add unlimited users, you can set this up for FREE !  You can read the post here. Patrick has a similar post on how to implement GTD in Backpack.
