Welcome to the site, I'm glad you decided to check it out! I bet you'll be making friends and starting stories in no time, just be patient with it and give it time! As always, for newcomers, I like to suggest checking out Newbie Navigation. There's a lot to iwaku and it can be overwhelming, but this should help you out :)
If you have any questions though, reach out to staff. We have the green usernames and are always around to help!
