Basically the idea is very much like the Survivor TV series, We start with 20 members and after 4 voting rounds we will have only one. Each voting round there will be 3-5 members the members of the forum will vote on, to vote off the contest. It will go like this
Starting with 20 members we divide them into 4 "Teams" of 5 and have 4 voting sessions go on at the same time. The next week the 2 members from each team that have the most votes are voted off, this leaves us with 12. On the second week we merge two teams together so we have 2 teams of 6 .We have another round of voting, and 2 get kicked off. For the 3rd round we have 8 members left and the vote will happen again with their 2 teams, so we end up with 4 members for the 4th and final round. The Final round has those 4 now being voted on to be the winner.
