Output "say" console messagesSuggestion
Please add the ability to see messages in the RustAdmin console that were transmitted through Rcon (for example, Battlemetrics).

    void OnRconCommand(IPAddress ip, string command, string[] args)
	{
    	if (command == "say")
    	{
			string saytext = "";
    		
    		foreach (string arg in args)
    		{
    			saytext += arg + " ";
    		}
			
			Puts($"[Rcon] {saytext}");
		}
	}​
You'd really just need to hook the OnServerCommand, as "say" is not unique to RCON. Also, there are plugins that do this, but also that isn't really the scope or purpose of this plugin.
Using OnServerCommand, I could not see messages sent through RCON Battlemetrics in the RustAdmin console.
	void OnServerCommand(ConsoleSystem.Arg _arg)
	{
    	if (_arg.cmd.Name == "say")
    	{
			string saytext = "";
    		
    		foreach (string arg in _arg.Args)
    		{
    			saytext += arg + " ";
    		}
			
			Puts($"[Rcon] {saytext}");
		}
	}


Also, I set up regex for BetterChat in RustAdmin:
^\[Better\sChat\]\s(?<sender>.*?):\s(?<message>.*)

so it’s better if all messages have a tag [Better Chat]
Better Chat doesn't modify the "say" command. If you're looking for such, Better Say might fit your needs.
