CloseOldPrivateDialogs <max_count>
Force closing outdated private dialogues for all users on the server, leaving only the most recent dialogues in the amount of "max_count".
By default, the number of dialogues can be empty, then the number will be taken from the server's srttings (by default 100). Specify any number above zero.
When the command is complete, all old dialogues will be closed, and all online users receive an updated list with private dialogues.
Close old private dialogues, but leave only last 10 for each user on the server:
mcserv: CloseAllPrivateDialogs 10
