Hello and welcome to Iwaku, Flame.
I'm Kitti and it's nice to meet you.
How did you find us, out of curiosity? Invited, search engine...?
Anyway, since you're new here, these are some useful places for you to 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 have questions, please don't hesitate to ask.
