Hello! Don't worry about the rust, we'll soon fix that >=P
We love RP on Iwaku, and all skill levels are welcome, so you can go ahead and jump in wherever you're comfortable and I'm sure you'll find it's just like riding a bike :P
The Content Boards are great for getting back on your feet and keeping your inspiration running hard and fast, too! We post writing exercises that hone your skills, and challenges that test your imagination; you'll be able to explore and learn more not only about writing your characters actions, but about their backgrounds, the world they live in, their hobbies, the items and creatures they interact with, and much much more!
