Hi, Rainbow! There's no reason to be shy here. Take your time to warm up to everyone and you'll find that everyone is kind and accepting! When I joined, I was very overwhelmed as well (In fact I think my intro post was "forums are scary", lol...) but it just take a little time to find your way!
I'll be more than happy to help you around, as well as Dragon, of course (It's his pride and joy).
Your avatar is just so adorable, I love warm and soft artwork like that, did you draw it yourself? If you did, I might just have to commission you c;
Anyway, we are all very happy to have you here, and I hope I'll see you around!
