This plugin allows authors, editors and administrators to communicate within the dashboard. Administrators will be able to grant which of those roles are granted access in the settings page.
The users will be allowed to communicate with each other using the built in WYSIWYG editor (TinyMCE). Users will be able to communicate with their team without needing any external services.

Author Discussion
