Hi Natalie,
Welcome.

I'm new too.
The forums here are so extensive, it's hard to know where to start. I decided to continue to read everywhere...as I'd been doing long before I joined in...and to focus my posting on this introduction area, in the area for my specific diet (which happens to be Atkins) and also in one other area where a particular member had touched my heart, I guess, and I wanted to give her support (even though that particular forum/area really doesn't apply to me). And I've stuck with those 3 areas...so I don't get myself confused...until I sorta learn the ropes and get comfortable here. And once I get more accustomed to posting here...I'll venture out into posting in more forums and possibly joining some specific groups and challenges.
Also, the active membership here is unbelievable. I've never seen a message board with SO many active members. It's going to take me some time to get to know people here.
There's a ton of helpful info here, especially in the stickies. This site is amazing.
