Hi SheaBDoll!
You might want to begin by going to the Support Groups forum:
http://www.3fatchicks.com/forum/support-groups-122/. There are groups by age, by weight, by interests, even "Chicks Up for a Challenge," where you can jump into some accountability challenge threads. (Even the ones that are monthly, people still join all month long.) Some threads are more active than others, so just take a look at the dates of the last posts to get an idea. People are very friendly here, and we love newcomers, so don't be shy! Take a look around and jump right in! Good luck!
