Well if you want to upload an image avatar for your profile, go to Profile(in the top bar of the page) and go to Forum Profile Information and choose to upload a avatar or use one from online. Also, right under that there is a personal text option, if you write something here, it'll appear by your avatar whenever you post.
It says Substitute Shinigami because that is your rank, based on posts. When you get to 50 you'll be a shinigami and after that you'll get to 3rd seat at 100 posts. Etc. etc.
