Hi Molly!
The chatrooms can be a bit intimidating when you first start using them. You can always go in and say its your first time and that you're nervous. Like Alex said, sometimes it can be a little rough, so you can always change rooms or try again another time.
I'd be happy to go in with you sometime if that would help! You can look at the "who's online screen" from the drop down menu and find me and any other mod/admin in bright green or red. If I'm online, feel free to drop me a pm and I'll go into chat with you if I can!
