The only problem with beginning of a game is timing it just right - if it's too soon, not all of the players will have connected in time to see it happen. Otherwise, as was already said a cron job every 30m which sends the data to the server would work fine. Perhaps if David sees this thread he'll paste the magic string we used before, I can't remember how it goes (netcat something \xff\xff\xff\xffrcon <rconpassword> cp Your Text Here)
