iirc there is a command but I'm not sure if you can use it.
Should be under TFstats, try digging through that menu and see what you can find. I'm busy and don't have time to boot up my game to check, sorry.
try /tfstats or something like that. It should be somewhere labelled "connection messages" or something.
if you can't find it, I'll see if I can get the command dug out once my 7 day work week is over and I get a day off.
