I was notified that I have a private message, what does that mean?
If you receive a private message, it means that the moderator/ admin needs to address your question or issue in private or requires information that may be more personal (such as an email address or account details). Only you and community moderators/admins can see the contents of the private message - other community members cannot see it.
