Ask questions in GitHub Discussions

Register a new support ticket only if necessary
If you are convinced that you identified a bug in xpm (if you have doubts, use GitHub Discussions), or you have a pertinent suggestion how to enhance xpm, register a New Issue in the GitHub Issues tracker.
Use of private e-mail
Sending private messages will be automatically replied with a link to this page. The reason for this rude behaviour is simply an attempt to use the time more efficiently; since GitHub Discussions are archived, other people having similar problems might benefit from the answers.
