A very simple chat for local networks that allows exchanging text messages and files, with the ability to demonstrate the desktop screen. It easily supports over 100 online users. The only downside of the program is the lack of a Russian language interface translation. And the most frustrating thing is that when trying to create a translation file, it is displayed in the program, but when switching, the text is displayed incorrectly, and changing the encoding does not help. It is also important to consider that all computers with this program must be in the same subnet of software/hardware routers and NAT.
