One thing to think about:
Dadadu66 added 2 players who are not registered at the forum. What about them? do we let them play? Because they can obviously not post that they won.
That's a good question. Based on the rules I came up with (this part is not something Dadadu66 and I discussed) they will not be able to participate unless they register on the forums and will post their cup results here. Not registering on the forums also means we have no means to contact them through the forum (nor by e-mail) to make them aware of the next cup round. Even if we were, if they do not speak English they may not understand these e-mails.
What do you say, Dadadu66?
I think they could be a problem... Before to delete their enrrolling, i think we could ask to alket if he could contact them to they come to the forum(with google translate, they could understand i think...)
Otherwise I think the idea of game 4 is not a good idea, because in 2vs2 could lose good players.
And there could be 1vs1vs1vs1 unofficial pacts.
About a prize, i don't know, what we could give like a prize except congrulations and the enjoying to play. ^^
Otherwise, why don't we based on the london hour ? why on the berlin hour ?
(Sorry i haven't answer at all, but there are much of thing to think, but i think the tomreyn organisation idea is globaly good.)
Concerning the organizers, i think they(we) could participate, but it there will be a minimum of 2participants to avoid cheats, it's the case here(me, tomr and titi), so i think there won't be a problem. Even more, i think i won't participate at the cup(like a player

).
