Well, I wasnt entirely sure as to where to post this. Basically, how can I edit tracks (e.g. add barriers to it, like in the cruise servers)? Do I need special software etc. What do I need?

Thanks,

Am i right or rong, but you do need S2 to edit tracks........right?

yes, you can't do it as a demo user.
