Some good points have already been made (you guys are fast...or reeeeaaaaly bored today
). I think we should all specify for which countries we'd like to play, so that we can see how many countries would there even be, or if people would even be interested to play FC (if only a few players apply or if we'd only have 2-3 countries, that wouldn't be much fun).
My suggestion is to allow as many players for any given country, but to (based on how many players/countries we have) allow teams to choose their players for each round of FC (they could pick those who recently had good results or something...). So that would mean, for example, tennisfan_77 and myself playing for Croatia in the first round, then * mladen * and volume3d in the next, something like that.
I also think that if two players from different countries want to play, but they're the only players for their respective countries, they could team up and play for one of their countries, or for some completely different country (for instance, if WhoAmI? and Broseghini want to play, they can play for either Estonia or Brazil, or for some country that is not represented in tipping).
Also, I think we should only play World Group 1, no play-offs or anything like that, the best four teams (regardless of how many teams we have) go to the semis, and the best two battle it out for the winner.
R1 is scheduled for early February, so we have more than enough time to figure everything out.
