FANBOX isn't just a service for creators who are already well-known. The moment you get started on FANBOX because there's something you want to create, you become a creator, too.
Activity diaries, rough sketches for future works, ideas that pop into your head – you can post it all to FANBOX. Get started at whatever pace works for you.
Then, when you get your first supporter, don't be shy! Leave a post or a comment, to tell them how much you appreciate them.
