"I've been using TD for over a year now, and have come to rely on it completely at work. Still working on getting more organized at home.
Either way, TD is one of the best task managers I've used in 14 years of using electronic todo lists. In it's free version, it's one of the most complete task managers available, including such features as Folders (anything you want them to be), Contexts (Customizable, usually things like work, home, errands), Status (Active, Next Action, Hold, Waiting, Someday, Delegated, etc.), Start and Due Date and time with extensive repeating task capabilities.
For a lousy $15/yr, they throw in sub-tasks and individual notifications and Goals (yes, finally I've found a task manager that can tie my tasklist to my goals at 3 different levels), but I'd pay it anyway, just to keep them in business. For $30/yr, they add document storage and a few other high level features. All a bargain no matter how you slice it.
This web app can be used by beginners or experts because you get to choose in the Settings which features you want to use. Like it simple? Choose one or two and go for it. Like to get serious? No problem, just choose all you can handle.
The Help screens are basic and need some updating, but are a good starting point. Beyond that, the Forums are some of the best in the biz, and the owner, Jeff, visits every day and replies to any posts that need his input, usually within a day. You can't beat that! Other users are there to help as well.
TD is one of the most powerful task managers available with some of the best support you could hope for - a great combination! And oh, yes, updates are frequent and responsive to user input, particularly to the input in the forums. It just doesn't get any better than this. Give it a try and you won't be disappointed!"
