It's nearly the end of the year, and I decided to enter my new years resolutions into RTM.

Lose 2 stone -resolution 31/12/10
Play guitar 2-3 times a week for 30 mins -resolution 31/12/10
Take 1 good photo every day in 2010 -resolution 31/12/10

I tagged each one with -resolution ("-" is my prefix for categories) with a due date of 31-Dec-2010 (if it was one with an earlier date, or a review date other than the end of the year, set it as appropriate).

When they come due I can review and see how I did.
If I really wanted to be nagged, I would set them up as repeating tasks every week or month.
