You don't have to go to each list, doing a search for due:yesterday will show you all tasks you should have completed yesterday. Delete, complete, postpone as you wish until the list is empty.

dawn.earl,
Regarding tasks disappearing, it sounds like you may be looking at the Overview or a Smart List confined to today; you may prefer to look at your lists or to set your Smart List criteria to look for other dates and/or undated tasks.

Hope this helps!

Thank you for your replies.

Andrewski: I am not looking at the Overview or Smart Lists. These are all lists I have created and added tasks.

Rajjan: I am afraid to do what you are suggesting because I just lost more tasks with notes while cleaning (i.e., deleting) everything up this weekend. I wish a deleted item could be retrieved such as in Outlook e-mail where a folder holds deleted items for a designated period of time. While I love RTM, I am seriously thinking of finding something else because I am losing valuable information. In this case, I lost notes from a doctor appointment with contact information for the follow-up. I didn't even realize it was gone until I went to find it. What else have I lost that I don't even know?? Very frustrating!

dawn.earl,
Sorry to hear you're having a difficult time with RTM.

In general, you don't need to delete any tasks; you may find that simply completing them is more effective for you. Completed tasks are available for you later, whether you want to duplicate or uncomplete them, or simply to refer to them and/or their notes.

Hope this helps! Post back if you have any further questions.

RE: In general, you don't need to delete any tasks;

If I put a due date on a task, but I don't delete the task, then I get scads of overdue tasks. That's when I go into each list and delete the overdue. Sometimes the repeat function "disappears", and I don't catch this. If I delete a task that doesn't have a repeat on it, it is permanently deleted.

What is the appropriate time to use delete?

LOL! I do agree that completing the tasks is more effective! Do you mean this literally or also marking them as complete (although I haven't completed them) in RTM?

Thanks! I so appreciate the help!

dawn.earl,
It sounds like you're making too many tasks repeat, so you're ending up with a lot of extra tasks.

A few high-level ideas:
* Create a list of the tasks you want to remember. Set due dates where appropriate, but don't set dates on tasks that don't need to be done each day.
* Don't make these tasks repeat. Instead, to make sure you keep an eye on all the tasks you want, consider creating a Smart List that shows the tasks you want to see (e.g. high priority tasks, tasks due within the next week, excluding tasks that you don't want to see right now, etc.). Let me know if you'd like some help coming up with a the right criteria for what you're looking for.
* For tasks you want to have dated but aren't able to complete on a given day, consider postponing them. You can check them all and click the Postpone button at the top; this will make them due today if they were overdue, or it will postpone them by one day.

Hope this helps! Let me know if I can help any more! :)
