Cherie, welcome to traineo! I can relate to your comment about updating your workout and diet information as that's something I occasionally find myself struggling with. Something that may help is if you commit yourself to updating that information every day at a certain time, or if you at least commit to visiting the site a time or two each day, so that way you really have no excuse for not updating it since you're already here.
I also think the community aspect is a good source of motivation that if tapped, could help you stay committed to your new lifestyle and to diligently recording your progress here. I've been a member here for 7 months (basically since Traineo began) and I'm just now realizing what an outstanding resource this place is.
I've decided that at the very least, I'll pop in once a day just to see what kind of discussion is taking place and while I'm here, I'll make an entry in my journal and log my workouts for the day.
Like I said, I think integrating yourself into the community and participating in discussion will at least help you get back here, and once you're here, tracking your information won't be as difficult.
I think traineo has all of the tools we need to successfully progress towards our lifestyle goals, it's just a matter of using them effectively.
Good luck and welcome!
