Is it just me or does the Message Center "Send message" option only let you send messages to those who have purchased from you?
If I go to:  https://marketplace.reallusion.com/backend/message-center?tab=direct-message
and click "Send message" I get the following.  I see no way to send a message to anyone else.  The "old" message system doesn't appear to let me attach files.  This one does but the person I want to send to isn't my customer - I am their customer.
