So I'm on Sparkpeople, I use it mostly to track my p90x workouts, sometimes I get the food into the food tracker too LOL. but the p90x team over there is awesome and very supportive!!
I love everything about that site, the people, the articles, it's just an amazing place to get your 'spark' going!!
you can check out my blog over there - I try to post often when I'm doing p90x, I find it's motivational for me.http://www.sparkpeople.com/mypage_public_journal_individual.asp?blog_id=4251617
