If you look at the demo server list in LFSWorld (Racers and hosts online), I think it doesn't show any other versions than the main versions (sub ver 0). I mean it shows V, W, X etc, but not e.g. X4.
I ment the LFSWorld demo server list. It didn't show X10 some time ago. Now it works. Besides it's Victor who does all the coding to LFSworld, so I have understood.
I'm an old school coder (or at least relatively old) and I consider hacker (or to hack) to have a positive meaning. Hacker means a good coder and hacking doing some (clever?) changes to code. It is only these people who have no long coding background who mix it with cracker and to crack, which is braking into networks and computers. So hacker=good, cracker=bad (except with butter, cheese and tea). But maybe I should stop using hacker so much, because many people get a wrong idea.
