1. Dug deeper into code.  I changed the settings in the WP Core files wp-includes > user . php : 

    

   /*
   * If a nicename is provided, remove unsafe user characters before using it.
   * Otherwise build a nicename from the user_login.
   */
   if ( ! empty( $userdata['user_nicename'] ) ) {
   $user_nicename = sanitize_user( $userdata['user_nicename'], true );
   if ( mb_strlen( $user_nicename ) > 50 ) {
   return new WP_Error( 'user_nicename_too_long', __( 'Nicename may not be longer than 50 characters.' ) );
   }
   } else {
   $user_nicename = mb_substr( $user_login, 0, 50 );
   }
   
   $user_nicename = sanitize_title( $user_nicename );

    

   AND

   /**
   * Filters a user's nicename before the user is created or updated.
   *
   * @since 2.0.3
   *
   * @param string $user_nicename The user's nicename.
   */
   $user_nicename = apply_filters( 'pre_user_nicename', $user_nicename );
   
   $user_nicename_check = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->users WHERE user_nicename = %s AND user_login != %s LIMIT 1", $user_nicename, $user_login ) );
   
   if ( $user_nicename_check ) {
   $suffix = 2;
   while ( $user_nicename_check ) {
   // user_nicename allows 12 chars. Subtract one for a hyphen, plus the length of the suffix.
   $base_length = 49 - mb_strlen( $suffix );
   $alt_user_nicename = mb_substr( $user_nicename, 0, $base_length ) . "-$suffix";
   $user_nicename_check = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->users WHERE user_nicename = %s AND user_login != %s LIMIT 1", $alt_user_nicename, $user_login ) );
   $suffix++;
   }
   $user_nicename = $alt_user_nicename;
   }

    

   AND I changed from 60 to 12

    // user_login must be between 0 and 60 characters.
   if ( empty( $user_login ) ) {
   return new WP_Error( 'empty_user_login', __( 'Cannot create a user with an empty login name.' ) );
   } elseif ( mb_strlen( $user_login ) > 60 ) {
   return new WP_Error( 'user_login_too_long', __( 'Username may not be longer than 60 characters.' ) );
   }

    

   Will open registration real quick to see if the change works. 

2. Forum registration has default 3 to 15 characters. Above that, it errors out. Good. 🙂
