Hello and welcome to Iwaku! If you didn't know, we are a roleplaying community. Have you looked at our Home Page? The 101 links are very useful for explaining what we get up to here and how things are run. ;) If you still have any questions or concerns after that, it's as easy as messaging one of the Staff here, myself included, and we'll help you out.
Yus, we roleplay here. >:3 But if you mean where to get started, I think the JumpIn section is the best cause you dun have to write a bio or signup for anything. You just jumpin and play!
