Joe's Goals is a pretty cool (and free) goal tracking site.
It lets you track daily goals, you simply click whether you did each goal or not. You can check a goal multiple times in the same day, and it also has negative/bad goals you can track.
You can also have it send you email reminders when you haven't logged anything for a day or two.
Not a perfect site, but useful and free. I recommend keeping it simple though, I don't find it helpful to include lots of detail and a long list of goals, but whatever floats your boat.
My plan is to track daily goals, my "Keys to Weight Loss" (see My Methods page).
Everything else is gravy (and I like gravy).
