Hello. On the zombie server a lot of Russian-speaking players. We understand simple phrases in English, and partly can answer, but the level of knowledge of the English language leaves much to be desired. But there are situations when you want to unite with the players, take up defense and stick together, fight off the zombies in a team, it’s very difficult to explain your sentence in English. I suggest to allow the Russian language, because Almost all the players from the countries of the former Soviet Union speak and understand Russian. If you are worried about the problem of advertising, insults and other violations using the Russian language, then you can make a couple of Russian-speaking admin and give them access only to the command !mute, i.e. it will be just a chat moderator, but not a server, i.e. admin without the possibility of kick, blocking, etc.
