I'm glad you're getting active with SparkPeople - it's a great community, wonderful resources and fantastic support.
In my experience, SparkPeople is 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 instead of a 'quick fix wonder diet' - it's about waaaaaay more than 'just' losing weight so you have definitely come to the right place!
If you ever need any help using features of the site, there are tutorial videos under the HELP section that can show you how to use the features of the site. You can also find them on the START page and several other places on 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! The FastBreak program is a good way to start.
Another nice thing about SparkPeople is that we have permission to be human - we don't have to change everything at once or be in a hurry to reach our goals. 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!
