The error shown when a teammate's name conflicts with a reserved name now lists \"user\" and \"system\" as reserved, in addition to the existing \"main\" and \"team-lead\" (in any capitalization).\n\n**Why**\n\nThis stops a teammate from being named something that would be ambiguous with the built-in \"user\" or \"system\" recipients.\n\n- Area: Teammates\n- Names: `user`, `system`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5"}
