Another warm welcome Andrew!
I guess you could say that the true definition of the 100 Plus Club, is that you have 100 lbs to lose, which you will find in the majority of the people that come on this forum. However, we would never turn anyone away, as we are pretty welcoming bunch.
When I first started "lurking" on the forum, and checked out all the different threads to see which one suited my personality the best. I think you will find that all the forums are very welcoming to new comers. However, if you choose to stay with us, there are a couple of weekly threads that are used all the time.
Journal Thread: This is where you log what you eat every day, and helps to hold yourself accountable to what you eat every day.
Points Challenge Thread: This is a monthly challenge where you log your excercise, water and if you are staying on plan.
Weekly Weigh In: This is where you can post your weekly weight loss (or gain).
NSV Thread: Non Scale Victories, this is where you can log other victories from losing weight, i.e. new clothes
Yadda Yadda Thread: This is a general thread where we post about other things that are going on in our lives, outside of our weight loss plans. This is where you really get to know the others that frequent the forum.
Other than that, you are more than welcome to post another thread if you have questions, comments or just want to make an announcement.
