There's something on this site for everyone, and part of the fun that I've had is discovering all that the site has to offer.
One of the first things that you should do is create your SparkPage, if you haven't already done so. This will allow other members to interact with you, and provide support. Just go to www.sparkpeople.com/mypage_home.asp to get started.
After that, you should check out some different SparkTeams, to find groups of people that will be your main support during your journey. You will find teams that cover everything from workout challenges, such as the Official 28-Day Bootcamp Workout Challenge ( teams.sparkpeople.com/28DayBootcamp ), to support groups such as the No More Smoking group ( http://www.sparkpeople.com/myspark/g roups_individual.asp?gid=758 ), to groups of people with similar outside interests, such as the Buddhist group ( http://teams.sparkpeople.com/Buddhis ts ).
If you feel overwhelmed and just want someone to talk to one-on-one, please feel free to visit my page and add me as a friend, or send a sparkmail. I'm always happy to help out.
