Welcome Tracey! I don't know what your interests are, but there are lots of teams here at Spark and I'm sure you'll be able to find one or two that will be a good fit for you. Don't hesitate to join a team and introduce yourself--and don't be afraid to "unjoin" a team if you find that you don't connect there. Just keep looking and you'll find a hometeam that will be supportive and where you'll make some good friends.
This is a wonderful site and you'll find everything you need to help you on your healthy journey. Everything, that is, EXCEPT a personal trainer to come and make you get moving!
