If you spend a lot of your working life managing emails, then a task manager that lives inside Gmail is going to sound attractive. Taskforce have come up with a very functional and minimalist task manager that is right at home within the uber email service. Users can run multiple lists for different users, link emails to tasks, add comments, deadlines and reorder tasks easily. Installation is extremely simple. Taskforce is free at the moment, but will eventually morph into one of the many excellent cloud-based services that (shock, horror) charge a little for their wares.
