What does 'Persistent Chat' mean?

Persistent Chat is a live chat software communications idea that consists of standing, topic-based chatrooms with a focus on real-time messaging. Persistent chat allows you to establish long-lasting topic-based discussion rooms. Persistent chat rooms are places where a group of people who share a common interest can connect and work. You can share and find ideas and information by browsing or searching the chat history, and you may share and find ideas and information by submitting messages in real time. You can use persistent chat to search for material both within and across rooms, as well as establish alerts (notifications) and filters (subject feeds) to keep track of talks in certain rooms and about specific topics. Additionally, you have the option to build and run your own chat room.
