Is there a module for the site that allows the administrator to communicate with registered users?

Question

PHP

There is a site, for a long time I have been looking for a module that allows you to organize chat-personal messages between the administrator and the registered user. At the same time, storing all correspondence in the site's sql database and having some kind of application for ios or windows, where you could receive notifications about new messages from users. Any online consultants like livetex are not suitable here, because. they do not determine which user is currently writing to me.
Maybe someone knows a ready-made solution,

Answer 1

Take some forum move in private correspondence.
