While you can change your Discord name after signing up, it seems that the initial user registration process may apply some sort of validation regex or something to the Discord ID provided by users, requiring that they provide an ID that ends with a # and four digits (i.e. Danny#3602) as per how old Discord IDs worked.
This is confusing to new users as Discord IDs now follow a different format, and any validation looking for a trailing #+numbers should be removed.
