NO! No different. Only different in your mind.
Do you think that we had anyone to help us? Nope. We had to struggle through it. To be frank, I have learned a little from every one of these tourneys. There is no correct way to do them. Since I do not know how you have these set up in your mind, I really can not help except to spread the word as much as I can.
So start thinking...
Since you want teams, what is the best way for players to form teams.
What is the motivation?
How do I sell the idea?
The fact is that most everyone here is a casual player of the game. I am now in a clan, so my gameplay is COMPLETELY different because I want to be an active and successful member of this group of people. That requires work on my part. To be successful, you need the same type of ethic from all of your teams. THIS will be the tough part.
So I challenge you to make it happen. As I stated above, I will help spread the word as much as I can. I leave the actual planning and creation of this event in your hands.
If I were you, I would first see if there is someone that would be willing to host these events. Won't do you a bit of good getting teams together and planning the scoring/elimination parts if you do not have a place to play.
I have no doubt that you can make it happen. Good luck to you. Let me know when you want me to start spreading the word.
