Currently, you have several options to control which users can send you personal messages:
- By default, any full user can message you
- There is a global option under Preferences -> Notifications called
Allow other users to send me personal messages. Disabling this feature will prevent all non-admin users from being able to message you
- Additionally, any user you add to your Mute or Ignore lists (Preferences -> Users) cannot send you personal messages (this feature was partly broken do to a recently corrected bug)
As of today, you now have a third option: Under Preferences -> Users, there is a new option
Only allow specific users to send me personal messages. Activating this option will allow you to create a list of users who may message you. All other non-admin users will be unable to send you messages.
Personal messages can be much more intimate than general posts and replies, and this third option will offer further control of who is permitted to send such messages for those who wish it.
Please feel free to respond here (or via a personal message if you prefer) if you have any questions or concerns. As this is a new feature, bug reports are also welcome on this topic.
