What helps with a bug report

• The tool you were using.
• Your browser and device.
• The steps that caused the problem.
• A small example with made-up names, and the result you expected.

Please avoid sending a private roster or sensitive information. We do not need your real list to investigate most issues.

There is no form that uploads your list. Contact email, when available, uses your own email service.
