SparkPeople is something like a in some ways - it's lots of fun and easy to make friends because we're all in this together. I like the way a HEALTHY LIFESTYLE is emphasized - it's about waaaaaay more than 'just' losing weight so you have definitely come to the right place!
There are tutorial videos under the HELP section that can show you how to use the features of the site.
If you haven't discovered The Spark book and/or the SparkDiet linked at the bottom of the START page, check them out - the program is simple but extremely effective. There is a TON of information on this site - so much it might even seem overwhelming but fortunately we don't have to 'digest' everything at once!
Take a few baby steps and then a few more and before you know it, you'll have completed a long journey - I hope you enjoy this community as much as I do - it teaches us how to make positive lifetime changes because that's the only thing that will work over time!
