Hello there and welcome to Iwaku, GAP.
I'm Kitti and it's good to meet you!
You should take that attitude and make it more excited!
It's not that you have to - you get to meet all of our super fun and friendly members, who will all be paying attention to you!
Since you're new to us, I have some links for you to help out with getting accustomed to our site! This is where you can sign up for the roleplays found in Modern, Scifi, Fantasy, and sometimes Mature. Generally, they will have you post a character sheet in their thread, a new sheet for each roleplay! You can also start signups for a roleplay of your own here.
This is where you can find jump in games, which typically have no sign up thread. You just start posting!
You should also take a look around on your own, but these links will hopefully help you out!
If you need help, please do feel free to ask~
