So, let's see, the classes to players list looks like this, after I added Scout to myself as a potential class: [is Non-Euro]
Scout: LASD
Soldier: [Mr.Person], [Dr, Johbson]
Pyro: Myroc, [SHADOWDUMP], [umiman], [Dr. Johbson]
Demo: [Bandages]
Heavy: [DoctorZ], fenrif
Engineer: Jreengus, [Dr. Johbson]
Medic: LASD, [umiman], [Dr. Johbson], fenrif
Sniper: [Bandages]
Spy: [dragnar], [Mr.Person], [Cheeetar]
Not participating: [Zai]
Also, from the FAQ:
Are non-European teams welcome?
Yes, as long as you are fine with playing on European servers and in European timezones.
So, it's all fine, except scheduling will be tricky.
Next important thing:
How many people can be in one team?
14 people can be registered to each team. Make another team if you have more players (eg Community Team A, Community Team B, etc.) You cannot play in more than one team.
So there's nice leeway as only 9 people are included in a round and the classes can be juggled between players too. Another team might be possible but it might get a bit iffy to find 28 Dwarf Fortress people wanting to participate in a competitive tournament.
Currently we have 12 people expressing interest, 3 of whom are a bit doubtful about joining (SHADOWdump, Mr. Person and Dr. Johbson), but I know a few people that haven't spoken up or noticed this who are likely interested. Let's keep listing and see what we can come up with, and if people will have the honor of joining the DFC or Bay12games B-team too.
Then the most important thing! (Not really):
Can you tell me more about the in-game medal?
The in-game medal will be like a hat. Everyone can see it.
You will win a medal when you A) Win the tournament (winners medal), B) Finish 2nd in the tournament (runner up medal) or C) Are eliminated from the tournament (participation medal). You do not get a medal for just signing up.
So, the tournament has to be finished to get the shiny, awe-inspiring, tiny medal.
