If you have computers at home and at work, you can access your tasks on both, and keep them in sync. TaskAngel uses Toodledo.com as a hub for synchronization with other computers.
You can see Toodledo for yourself at www.toodledo.com. You can open an account there, free of charge. Or TaskAngel can create an account for you. See Using TaskAngel with Toodledo.
TaskAngel will pass changes back and forth with Toodledo, so that multiple versions of TaskAngel on different computers are all kept up to date, so long as you keep them synced regularly. TaskAngel syncs with Toodledo automatically every hour, while you are connected to the Internet.
