Hello! With the latest update to the website, newly registered users will need to request access to upload avatars and profile backgrounds.
This is being done so we can limit the abilities that bots and throwaway accounts have on the website and to ensure that those who are using the forum are actually real.
You can do this by responding to this thread, letting myself or one of the other admins in Discord know, or by emailing us at contact@tenchiforum.com.
