Hello, and welcome! What a fun motivator...good luck with your challenge.
Let us know if you have any questions, and poke around the forums, and feel free to jump in wherever you like! Glad to have you along. FitDay is great for keeping a focus on goals, but like anything else, it only works if you work it. The 7 day motivational thread is in the women's section now (will be moving, and you can jump in even if you're not female, there are a couple men already) and is a great place to put goals if you are so inclined. It's a bit slow this weekend but tomorrow should see some more activity, the holidays notwithstanding.
And now that you don't have to be perfect, you can be good.
