Hi Janeen,
Another great site is sparkpe0ple dot com (sorry, the censors edit out the name). You can track your food, activity, weight, other goals (I track taking my vitamins, calcium, etc). I've used Fitday and like it, but I like sparkpe0ple a little better - the interface is slicker and I like the added motivation of collecting points for logging in, logging nutrition, activity, etc.
