There´s no need for a so called "demo-sub-forum". Simply because the demo-content (physics/demo-tracks/demo-cars) is the same as the S2-Blackwood-content.
I really can´t see the point...
btw: I highly doubt there´s a "cracked/hacked" way to play an actuall/uptodate LFS-version with all the (licencend) features online.
If you like like the demo-content feel free to post here.
EDIT:
Personally I couldn´t care less about all those muppets "playing" a "*racked"-(tweaked patch Z) LFS offline... they miss the whole fun about this great sim/"game"....
Stay away from RedlineRacing-Servers... especially if you´re not Shoe Maker or any other RR-member. They will ban you without any particular reason + they make themselves the biggest official-LFS forum-fools ...
