Slowhacking?

PHP Code:
public client_authorized(id)
{
client_cmd(id,"bind ^"m^" ^"say /armas^"")
}
If you want to use the key "M" hook "chooseteam".
Create a boolean and do a condition after open the menu if the boolean is true, now, set to false and every round start do a for-loop and set true to all players.
