ok so i just joined RTM, and it's really cool. i wrote down all the tasks i need/want to do and RTM helped me organize them into these great lists with all these cool properties, tags, etc.

now all i'm having trouble with is figuring out how to get RTM to remind me of the tasks i want to be reminded of, but only WHEN i want to be reminded of them.

the first problem i'm encountering is that it seems that RTM can only remind me of tasks that have due dates. the problem is i find a lot of my tasks don't have an official due date, but i still need reminders for them to get them done in a timely manner. and even the tasks with due dates i can only be reminded of either the day they are due, or everyday between the day they're due and an earlier day that i set. of the two choices i would most likely go with the 2nd (choosing an earlier day to start being reminded). but the problem with that is there might be certain days within that time that i can't get to the task and i don't want to be bothered with reminders for them. i can foresee that if i'm regularly being reminded of tasks that i can't do, the reminders will start to seem "ignorable" and they will lose their power.

ideally, i'd like to be reminded to do a task ONLY when i'm able to do it. (this also goes for tasks without due dates.) obviously, RTM can't read my mind and know which tasks i'm able to do on which days. i'd have to look at my calendar and figure that out on my own. but once i do figure that out, it would be great if i could somehow set it so RTM reminds me on those days to do those tasks.

if there's a way to do this, please let me know.

or if there a better way to go about this that i'm just not thinking of, please clue me in!
