RTM, Remember the Milk is great. When I have a task that I think of I can make a note of it, in case I cannot do it right then.
The task list is great to look and see what I have rated as Important for today.
Good folders for Personal, Study and Work. Easy to add task, and easy to Postpone the task with the little "+" button.
The TAGS are neat, I have to do more learning on those, but a neat way to tie the tasks into another "view". Like related to my kids or an activity.
And the notes section is good. And I use recurring tasks a bit so far.
GREAT work RTM team !!!
