Welcome to the boards! Doingmybest gave some awesome tips, and also, if you're up for group challenges, and being part of a team, there are loads of quests out there.
The chicks up for a challenge (I think I got that right) section of the support board is a great place, and then right here is good too. There's a Christmas challenge that anyone can join in. Just think of a good, obtainable amount of weight you would like to lose and put that as your goal when you join. We'd love to have ya over there.
Also, maybe journal for a day or two just to see what your normal caloric intake is. Make adjustments at that point, and if you have a nice place to walk. Go out, walk a bit and just move. You can also check out the TDEE.
Again welcome, and sorry if my post is a little out there. About to pass out.
