The link works fine! May want to retry it for those it didn't work for.
The only way they will ever have a 24/7 station is if the networks (foxtel, austar, optus) get the major corporations to spend their money on advertising and promotions. Otherwise there's no money in it for them, and no point in pursuing such a project.
The petition has a goal of a 1000 sigs. They need like 1,000,000 to make the networks sit up and listen, and see that it is worthwhile. Probably why it hasn't worked in the past, but I believe it is possible to get 100,000 and that would be a very good start.
Anyways that's my 2 cents.
