Mark James and Ben Keene, both 26 and from the UK have set up Tribewanted to invite people to join a tribe by registering for one of the 5,000 places available.

This is not just an online community. You actually become part of a Tribe on a real Fiji Island.

Basically you buy yourself a 2nd life. During vacation you actually can visit the Island for real. The other time of the year you live in the Tribe online and share decisions and so on.

I call it 1 Million Dollar idea, because a standard membership for 1 year sells for $210. There is a limit of 5,000 places (4,950 are still available). If they sell all 5,000 places the two guys net 1 Million Dollar per year. They also offer higher priced memberships see table below.
They just need to get banner up on ABC's Lost TV show site and the 5,000 places are sure gone in an hour.
Available Tribewanted Memberships:
Nomads – 1 years membership of tribe + 7 nights stay on island> £120 / $210
Hunters – 2 years membership of tribe + 14 nights stay on island > £240 / $420
Warriors – 3 years membership of tribe + 21 nights stay on island > £360 / $630

Visit the Tribewanted site for all the details and sign-up information.

The Million Dollar Homepage is also an idea from the UK. That one still wins in terms of the least effort to earn a million dollars online.
