Multisite Ticket System Wordpress Plugin - Rating, Reviews, Demo & Download

Plugin Description
Multisite Ticket System is a plugin for WordPress Multisite Network. Super Admin receives tickets and manages settings (categories and e-mail addresses). Administrators of the sites (only) can submit tickets. The plugin also provides comment sections for updating tickets.
There are a lot of WordPress Ticket System plugins out there, but rarely ones (or none) that are intended for improved communication between Super Admin and Site Administrators in a Multisite Network.
This is all the more convenient if your organization manages many regional groups throughout the country or in general manages many sites that are administered by different people with diverse kinds of WordPress knowledge, especially by people with zero knowledge of WordPress. In these cases, the Super Admin is able to help more efficiently through this ticket system, e.g. instead of managing requests via e-mail.
It means in effect that the ticket system is used in the backend (Dashboard) and doesn’t provide e.g. contact forms in the frontend (actual website / blog) for visitors. That what makes it rather interesting – a plugin for improved support in multisite networks.
The plugin has been developed in German, but English translation files are provided (US, GB, AU).
Since there has been quite a few changes in WordPress itself, the plugin has been tested now in WP version 4.4, 4.4.2, and 4.8.2, but of course it is possible that it works in older versions as well. Test / Use at your own risk! (And maybe contact me, too, I am happy to make this plugin compatible for as many versions as possible.)
