Toodledo is one of the first really popular cloud computing services, where your personal to-do lists are held on a secure server on the other side of the world, and accessed over the web. You can find out all about Toodledo from their web site at www.toodledo.com. If you are already a Toodledo user, you can use TaskAngel with your existing account.
TaskAngel gives you all the richness and immediacy of a desktop application, with the addition of Toodledo as a synchronization server. This gives you a number of benefits:
Backup: Toodledo acts as a secure backup server. If you lose your local copy of your task list, you can get it back from the server.
On the go: Hand-held devices such as the iPhone and Blackberry have the ability to sync to Toodledo, so you can easy feed changes back and forth between them and TaskAngel.
Work and play: You can keep one copy of your task list on your work PC, and another at home. TaskAngel sync keeps them up to date with each other.
To sync with Toodledo, click on the Sync button
in the TaskAngel toolbar. The first time you do this, a window pops up for you to enter the details of your Toodledo account. If you don't have a Toodledo account, TaskAngel can set one up for you.

TaskAngel then automatically signs into Toodledo and syncs your projects, contexts and tasks. The progress of the sync is indicated in the status bar at the bottom of the TaskAngel window.
If TaskAngel reports that it cannot connect to Toodledo, you might be being blocked by a firewall. See Internet Connection Problems.
After sync is complete, you can go offline if necessary and work on your tasks as normal.
TaskAngel will sync your tasks automatically every hour, as long as you remain connected to the Internet. To disable this, uncheck Auto Sync on the Sync menu.
When you are using Auto Sync, you can use the Instant Sync option. This syncs with Toodledo whenever you make a change, rather than waiting until the hourly sync becomes due. TaskAngel waits for one minute to make sure you have finished making your changes, then syncs with Toodledo.
The sync menu also provides a Renew Sync option. You can use this if you want to change your Toodledo settings. You can also use it if you think Toodledo and TaskAngel have fallen out of step.
Please note that TaskAngel does not currently support every feature of Toodledo. For example, advanced repeats are not supported in the current version of TaskAngel.
If you want to use Groups and Subtasks, you will need a Toodledo Pro account.
The Sync menu contains a further menu item - Get Proxy Info. You won't normally need to use this. It's provided to help troubleshoot Internet connection problems.
