Organization / reminders / to-do / project-planning web site?

I just signed up with Backpackit, and while setting up my pages I got goose bumps.

I had done this before. No, not at this site. At another one. There are to do lists and organizational tools there as well. I can remember putting some stuff on a to do list. I can remember thinking that it could one day become a very helpful setup for me.

Now I can't find it. It's orphaned, a free account on some random helpful web site somewhere.

Anyone know of web sites like that? Heck, how about good Google search terms?

edit: FOUND IT!!! Remember the Milk.
