SPW, I think splitting the players into groups would kill the whole "everyone play against everyone" spirit of EAC, which makes it so damn great in my opinion.
We had a little talk with Random about this long before the event even started and we agreed that for next year, we would implement a small app to the website that would make this whole process very very easy.
The idea is simple: before a week starts, you log in to the site and simply fill out a little timetable for the next week. All you have to do, is simply click on the times and fill out the whole table with "Free" "Busy" or "Unknown". A rule should force you to do this, say, until Friday midnight, else you get some sort of a warning, punishment, whatever.
Then, when both you and your opponent are done with this, the app automatically creates a timetable, maybe with some fancy colors and whatnot.
It would basically show us the same table that you made with "Europeans versus Americans", but personalized to both users. Whereever there is a green time, that means both players are free at that time
that week.
Your schedule can of course differ each week, that is why you would have to do this every week.
After that, you select one of the green times, by that, you suggest that date to be the final, and when your opponent accepts that, the time and date is fixed and it appears on the Schedule page.
This is the rough idea, this would make it very easy to fix the times, could add a few different things if necessary, like a points system that would measure how active and willing someone is to fix their dates, some sort of a system like that, and when you play against your opponent, the player with the higher points has the right, ability, to suggest the date first. Basically, that would make the less active or "interested" player having to adjust to the other. This is just another idea I had now, don't know if it would make any sense.
Well, the wireframes of the idea was said, we have got like a year to implement it and perfect it for next year's page, I think it could work perfectly and is a much much better system than this forum thread thing.
