Hey Sarah!
Welcome to TeenHelp! My name is Alessa and I'm one of the many buddies on this site. We have light green usernames and help new users feel comfortable and get started. You are welcome to ask us any questions you may have about the site. Glad to see you have already started posting on the forums! Feel free to stop by the Arrivals and Departures forum to introduce yourself and learn about all the features here on TH. Stop by the chat room sometime too! It's lots of fun in there and you'll make lots of new friends. If you need anything at all, don't hesitate to ask me.
Take care,
Alessa
