Hi, Alyssa Lee! Another tall girl!! I'm always happy to see other tall girls.. There aren't that many of us where I'm at
Check out the Chicks up for a Challenge section. That's where I got started. Lots of cool little challenges and check ins there that you can take part in. There's also threads for different age groups or faiths, if you're into that, as well as diet threads, if you're following a particular meal plan. Lots of places to go here! Very friendly, helpful, motivating ladies (and guys) here to steer you right.
As far as the stickers? Like the little signatures and sliders stuff? That comes after 20 days as a member here and a minimum of 20 posts. Can't wait to read up on your progress!!
