Welcome to Iwaku, Spiritfire.
I'm Kitti and it's good to meet you.
There's no need to be shy, you'll soon find that we're positively bubbling with enthusiastic and friendly people!
To help you hit the ground running, since you're new, here are some good places for you to make sure you check out!
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!
If you need any help, please don't hesitate to ask for it~
Happy roleplaying.
