Olá,
I think that this tournament can be a good idea, but the fact is that BZFlag - aswell the whole internet - isn't supposed (in my opinion) to create borderlines. I believe that it would be much better to make a tournament with the official teams - that would solve the problem of people from UK, or Denmark, or Portugal, etc, who don't have mates to play with.
I'm thinking about making a real tournament, where every team plays against every team (I don't understand this one, where USA played 12 matches and Croatia played 2 so far - in a tournament teams play the same matches), with stage groups, quarter-finals, semi-finals and final, all this sheduled (very flexible, of course).
The only atraction of this IST is the fact that one can see Chestal playing with FantaZee

That is a show I wouldn't like to miss!

P.S.: when I present this tournament I am thinking of to you guys it'll be all organized, with webpage, etc, etc, etc.
