Hi all, I'm looking for a task management service or app that works well with collaboration or teams. It doesn't even necessarily need to be for iPad. If there is an iPad app, cloud sync to a desktop or online service is a priority to me. 'Things' is a favorite of mine, but I'm starting some major projects with collaborators and assistants and being able to share and track each others to dos is a must. I've been playing with Action Method and I like it. It's missing some simple features like "scheduled" tasks that disappear until programmed to return to the forefront. So do any of you have any suggestions for some task management services? Thanks!
