I talked with Shadow (and EvilMike, who'll probably also help out with organising) about how we're going to do the tournament.
It'll work like this.

The 8 clans will be splitted in 2 groups of 4 clans each. As an example, I'll call the clans AA, BB, CC, DD, EE, FF, GG and HH. Let's say that group A has AA, BB, CC and DD, and group B has EE, FF, GG and HH.
All clans in each poule will have to fight eachother once, so 6 matches in each group, 12 matches in total in round 1.
In group A:
AA vs. BB
AA vs. CC
AA vs. DD
BB vs. CC
BB vs. DD
CC vs. DD
In group B:
EE vs. FF
EE vs. GG
EE vs. HH
FF vs. GG
FF vs. HH
GG vs. HH

Each victory will give the clan 2 points. From each group, the clan with the most points and the clan with the second most points can proceed to the next round. Let's say from group 1, AA had most and BB had second most, and from group 2, GG had most, and HH had second most.

The clan who scored best from group 1 will have to fight the clan who fought second best from group 2, and the clan who scored best in group 2, will have to fight the clan who fought second best in group 1. So that would be AA vs. HH, and BB vs. GG.
Let's say that HH and GG win. Then HH and GG have to face eachother in the final match, and the winner of that: winner of the tournament.

Simple ;-P


Edit: Most likely this will be what happens if lets say clan AA gets 6 points, BB 2, CC 2 and DD 2. BB, CC and DD would have to play 2 vs. 2 sudden death matches against eachother (sudden death: first team who scores a point wins). BB vs. CC, CC vs. DD, DD vs. BB. Those can be played quickly and won't slow down the tournament much.. Could all be done in 1 weekend, if it happens.
