Organization has never been one of my strong points. I do fine with the big things like planning for vacations but not with the day-to-day stuff. Now there's a site that helps people keep track of their to-do lists.
Remember the Milk lets you enter work, study, or personal tasks and sends a reminder by email, IM, or by SMS to your cell phone. You can prioritize your tasks and decide how long in advance you want your reminder. You can share tasks with co-workers, a study group, or friends and family by adding them to your contacts (they also need to have you on their contact list).
And it's free.
Actually my problem is probably more one of procrastination than it is one of not remembering what I need to do. Having an email or a message sent to my phone could provide the nagging I need to get things done.
