This was posted by Spadge in this thread (http://forum.team17.co.uk/showthread.php?t=25794). I suggest you all read it and obey it:

Mess around with stuff OFFLINE if you like, however this stuff will not work for online - and that's where we have issues. Instant bans for anyone taking this stuff online - sorry but we need a stable online community where we can.

Also, many such modifications are likely to break on lower-spec machines.

(Totally frag frame rate, playability and such).

The results aren't likely to be good. And it's hardly rocket-science hacking, so don't credit yourself so much! All the values are there in English!


So, in short, Team17 don't mind (to some extent) tweaking the game, but KEEP THE TWEAKS OFFLINE

You also tweak at your own risk!
