Hello! Please state your Discord account name, including the last four numbers of the account so we can verify that it’s actually you who joined the server! If you do not verify within the next 48 hours, the account we believe to be yours will be kicked from the server.
Only admins can change file names - therefore, the only thing regular users can do is giving those files the correct name before uploading. If you see you've made a mistake, you can upload it through the Upload Image option and change the name in the white bar.
