Ooh, roleplay newbies. Tasty, tasty newbies.
To teach all our witchery and eccentricity...
Ahem, hello! I'm Kitti and welcome to Iwaku.
It's a pleasure to make your acquaintance, WW.
Since you're new to roleplaying, I have some awesome links for you to check out to help you get started.
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!
This isn't a full directory of the site, but those two links are useful for starting to roleplay.
If you need help with anything, don't hesitate to ask. :]
Happy playing.
