Since now this platform is Open Source I would like to ask developers to add a PM (Personal Messages) on Steemit.
All social platforms allow users to send personal messages, and I just don't understand why it has not yet been added to the Steemit.
Furthermore, the community really needs it, because right now people send messages using comments of the SD transfers.
So, what I suggest: add a page in the profile section that will be hidden from the public. This page should contain a list of received and sent messages. Users must be able to respond, delete and compose new messages. Received messages should have a flag icon to mark spammers.
