Hey Kali -
Tickers are restricted to users who've been here for at least 20 days and made at least 20 posts, due to spam problems. Stick around and you'll get yours in no time!
You may want to check out our "Calorie Counters" forum, or the "20-somethings", for those in that age range. There are lots of other miscellaneous spots, challenges, and other things to explore, so look around.
Can't wait to get to know you better!
